وصف المنتج
The A series is the compact ceiling air-cooler line for commercial cold rooms. Three fin pitches map to typical storage bands: 4.5 mm for medium-to-high temperature (~0 °C), 6 mm for medium temperature (~−18 °C) and 9 mm for medium-to-low duty (~−35 °C). Models use electric defrost, internally enhanced copper tubes and external-rotor fan motors suited to cold-room duty.
Published tables list cooling capacity, fan count and diameter, airflow, motor power, heat-exchange area, defrost load, expansion and connection sizes. Naming follows capacity + electric defrost (E) + fin pitch + fan arrangement — for example A3.5E4.5-301 through A35.1E4.5-503 on the 4.5 mm range. Pick fin pitch from the product temperature first, then match kW against room load after correction factors.
مجالات الاستخدام
- Fruit and vegetable cold rooms (~0 °C)
- Frozen food and logistics rooms (~−18 °C)
- Deep-freeze and low-temperature storage (~−35 °C)
- Butcher, bakery and retail back-of-house coolers
الميزات
Three storage bands
A4.5 (~0 °C), A6 (~−18 °C) and A9 (~−35 °C) tables so fin pitch tracks frost load and storage class.
Electric defrost
Coil and drain-pan heaters sized per model; defrost kW is listed alongside capacity in each table.
Compact ceiling pack
Single- and multi-fan layouts from Ø300 mm upward keep the cooler clear of traffic while covering small to mid-size rooms.
Serviceable circuit
Internally enhanced copper tubes with documented expansion and connection sizes for installers.
