Common questions on refrigerant gases, packaging and cylinders, technical documents, quotes, shipping and product use.

Products

The ACC Refrigerant range includes R134a, R404A, R410A, R32 and R407C. If you are not sure which gas is right for your system, we recommend checking the equipment nameplate or the refrigerant code specified by the manufacturer. Share the information you have with us and we can help you find the right product group.

R32 is a pure HFC refrigerant used in new-generation split air conditioners and many heat pumps. It is class A2L — a mildly flammable gas. For that reason it must be used only in equipment designed for R32, at the charge specified by the manufacturer and under the stated service conditions. Contact ACC İklimlendirme for technical information or stock availability.

R410A is an R32/R125 blend that has been widely used for many years in split AC, VRF/VRV and heat-pump systems. Operating pressures on R410A systems can differ, so service equipment must also be rated for this gas. If you are not sure which refrigerant your unit uses, you can share the nameplate information with us.

R134a is a pure HFC refrigerant used in many vehicle air-conditioning systems, medium-temperature commercial refrigeration and some chiller systems. Not every unit runs on R134a; product selection must follow the gas code specified by the equipment manufacturer. Contact us if you need stock or packaging information for R134a.

R404A is an HFC blend used in low- and medium-temperature commercial refrigeration, cold rooms, display cabinets and transport refrigeration. Because of its high GWP, many new systems are moving to alternatives. On existing R404A equipment the manufacturer’s gas code still applies. Contact ACC İklimlendirme for stock or packaging on R404A.

In general, no. The fact that two gases are used in similar applications does not mean they can be swapped directly. Operating pressure, compressor oil, safety class and system components can differ. Selection must follow the refrigerant code specified by the equipment manufacturer, and different gases must not be mixed in the same circuit. If you are considering a refrigerant change, we recommend obtaining approval from the manufacturer or an authorised technical service first.

In zeotropic blends such as R407C, the saturation temperature does not stay at a single value during phase change; it varies across a range. This behaviour must be taken into account in charging and service practice.

In the ASHRAE classification, the letter indicates toxicity and the number indicates flammability. A1 means lower toxicity and no flame propagation in standard tests; A2L is mildly flammable with a low burning velocity; A3 describes refrigerants with higher flammability.

GWP is the value used to compare a refrigerant’s contribution to global warming against CO₂. ODP indicates the potential to damage the ozone layer. When comparing these figures, also check which standard and time horizon were used. We state the reference values used on our product pages.

Packaging & cylinders

Refrigerants are supplied in pressure cylinders, but cylinder size, net fill and valve type are not the same for every product. If you have a specific gas code and quantity, share them with us. We will check the packaging options in stock for that product and give you a clear answer.

Keep pressure cylinders upright as far as possible, secured against tipping, in a well-ventilated place. They should also be kept away from heat sources and direct sun. Storage requirements can differ by product; always check the instructions in that gas’s SDS/MSDS before storing.

Laying pressure cylinders on their side at random is not correct. Transport and storage methods can vary by cylinder type and product, but securing the cylinder and protecting the valve from impact are basic safety points. For the exact practice, follow the product SDS and the applicable transport rules.

No. Not every gas is offered in the same cylinder or fill quantity. Packaging options can vary by product, supply programme and order volume. Tell us which gas you need and how much, and we will check the cylinder options available and get back to you.

This depends on the product and how it is supplied. Some products may use different packaging or cylinder arrangements. If you tell us which product the quote is for before ordering, we will also clarify return and deposit terms for that cylinder.

The label is needed so product identity, safety class and required warnings can be followed correctly. Cylinders with an unreadable label or unverified product identity must not be used.

Yes. Pressure cylinders must be protected from excessive heat and direct sunlight. For storage conditions, follow the temperature and safety instructions in the product SDS/MSDS.

Technical documents

An SDS/MSDS is the Safety Data Sheet: it covers the product’s hazards, safe use, storage, first aid, fire-fighting, exposure and transport information.

A TDS is the Technical Data Sheet: it summarises the product’s main technical properties and application-related information.

A CoA (Certificate of Analysis) shows analysis results for a specific production or filling batch. It can be requested for shipments that need tender, quality-control or batch verification.

Write to us through the contact form or by email. It is enough to state which document you need for which product — for example “R410A SDS” or “R134a CoA” — so we can find the file faster. We check the current document we have and get back to you.

The documents required depend on the tender specification and the product. SDS/MSDS, TDS, CoA and a product catalogue are often requested; some tenders also ask for additional commercial papers. Send us the document list from the specification and we can check, item by item, which files we can provide.

Usually no. A CoA is most often issued for a production or filling batch, not for a single cylinder. If you want to know which lot or shipment a document covers, share the product and batch information with us and we will check the relevant file.

Orders & quotes

You can reach us through the contact form, email or WhatsApp. Telling us which product you need, an approximate quantity and the delivery city is a solid start for a quote. For equipment requests, sharing capacity, application or room dimensions helps us offer a more accurate option.

Refrigerant and equipment prices are not set by product name alone; quantity, packaging, current stock and delivery location can all affect the price. That is why we prepare an up-to-date quote for your need instead of publishing a fixed list price. Share the product you need and the quantity, and we can give you a firm price.

The minimum order quantity may not be the same for every product. Packaging, current stock and how the gas is supplied can affect this. Write to us with the product and quantity you need, and we will share the sales terms that apply to that item.

It is enough to send us the product code and an approximate quantity. We check current stock and, where relevant, share other cylinder or packaging options as well.

Yes. We also work with companies that buy regularly or use product in bulk. Share the products you are interested in, your approximate monthly or yearly need and your delivery region, and we can review a suitable supply option together.

Quote validity can change with stock, currency and transport costs. That is why each quote also states the date until which it remains valid. If you decide after that date, we may need to re-check the current price.

Payment terms can vary with the nature of the order and any existing commercial arrangement. We state the payment and delivery terms that apply to you clearly on the quote we prepare.

Yes. If you have an equipment nameplate, the current refrigerant code, the application or basic project data, share them with us. As ACC İklimlendirme we help you narrow the right product group and find the correct product. If a change to a different gas or equipment is involved, final technical suitability must still be assessed against the equipment manufacturer’s data or an authorised technical service.

Delivery & logistics

Yes, we ship to different regions of Turkey. Which product is sent, how much, and the delivery city can affect the transport method. When you share these details, we state a suitable shipping option and an estimated lead time on the quote.

Freight cost depends on product type, quantity, packaging and delivery address. Because refrigerants move in pressure cylinders, transport conditions can also affect cost for some products. When you share the delivery location, we show the shipping option and its cost separately in the quote.

Lead time depends on whether the product is in stock, the order quantity, packaging preparation and the shipping plan. We check these when preparing the quote and tell you an estimated delivery date up front.

Yes, we also review enquiries from abroad. Product, quantity and destination country can change transport and document requirements, so sharing these details from the start matters. If you also need SDS, CoA or other commercial documents, tell us and we will prepare the quote accordingly.

Export documents depend on the product and the destination country. A commercial invoice, packing list, origin statement, SDS, CoA or dangerous-goods transport papers are among them. Share the destination country and the document list you have been asked for, and we can check together which files are needed for that order.

Depending on the product classification, dangerous-goods transport rules may apply. When a transport plan is prepared, the product SDS and the relevant regulations must be taken into account.

Technical use

The first thing to check when selecting the right gas is the refrigerant code specified by the equipment manufacturer. Operating pressure, lubricant, safety class and compatibility of the system components must line up. If you have a nameplate or technical data, share them with us; as ACC İklimlendirme we can help you find the right product group. If an existing system is to be switched to a different refrigerant, the final technical decision must still follow the manufacturer’s data or an authorised technical service.

No. In a normally operating closed system, refrigerant is not a consumable. If the charge is low, a leak or a previous service job should usually be investigated. The leak must be found and repaired first, then the system recharged to the amount specified by the manufacturer. Simply adding gas on top does not fix the cause.

For zeotropic blends such as R407C, charging is usually done from the liquid phase to keep the composition. In service work you should not rely on general guidance alone; always check the product’s technical documents and the equipment manufacturer’s service procedure.

The compressor oil must be compatible with the refrigerant so oil returns through the system and the compressor runs safely. A refrigerant change must not be done by swapping the gas alone.

No. In a healthy, leak-tight air-conditioning or refrigeration system the gas does not “run out” in normal use. If the level has dropped, there may be a leak or gas may have been lost during an earlier service. In that case find the cause of the leak rather than only adding gas.

Using the wrong refrigerant can change operating pressures, reduce performance and create a mismatch with the compressor oil. More importantly, it can create a safety risk and serious equipment failure. Do not use a product other than the gas stated on the unit or in the manufacturer’s documents. If you are unsure, share the equipment nameplate with us and we can check the right product group together.

No. Charging, recovery, vacuum work and leak repair must be carried out by trained HVAC/R technicians with suitable equipment. Technical content on the website is for product selection and information; it is not a service or installation manual.
