Housing
The standard housing is made of aluminium (lines 040, 045, 050) or galvanized steel sheet (lines 063, 071, 080, 091) with powder coating in RAL9010. Optional: Housing made of stainless steel.

Heat exchanger coil
The tube system is arranged in line with stainless steel tubes, Ø 16 mm. Fins are made of pure aluminium with a distance of 4, 7, 10 or 12 mm between the fins. The refrigerant connection is located on the right side in air direction. To avoid oxidation the heat exchangers are generally welded under inert gas. Optional: Fins made of epoxy-coated aluminium

Defrosting
The electrical defrosting in heat exchanger coil and tray is wired ready for connection on a terminal box according to EN 60204-1. Hot gas defrosting in coil and tray, also available with integrated non-return valve. Separate hot gas or heat transfer medium circuit in coil or tray possible. In case of using water defrosting the total height of the unit increases by approx. 100 mm. For the operation at low cold storage temperatures we offer electrical fan ring heaters.

Drip tray
The drip trays are made of AlMg3 with a powder coating in RAL 9010. The condensation drainage is made of polyamide. The connection is threaded. The drip trays are tiltable for cleaning purposes. For rooms with temperatures below -25 °C and chill rooms we recommend using insulated drip trays. Optional: Drip tray made of stainless steel.

Sound pressure levels
The sound pressure level is indicated at 3 m distance according to DIN 45635, part 14 without reflection. Since cold storages have only a very low absorbing capacity, we recommend anticipating a small decrease at other distances. The indicated value is only a reference value. The actual sound pressure level must be calculated on basis of the sound power level and taking prevailing conditions into account.
