 Coil execution

Tube Pitch	38x33 mm square
Fin Spacing	4 mm : Suitable for applications with air temperatures from 10°C. 7 mm : Suitable for applications with air temperatures from 2°C or with expected frost.
Tube material	Copper 12 mm I = internally enhanced tubes for refrigerants P = internally plain tubes for coolants
Fin material	Goedhart aluminium ht-fins

A good thermal with the fins contact because the copper tubes are mechanically expanded into fully collared aluminium fins.  The suction header is executed with a Schräder valve for testing applications

All evaporator coils for refrigerants are pressure tested to 40 bars.  All evaporator coils for coolants are pressure tested to 15 bars. PAC aircoolers are supplied with a light overpressure charge.

Casing

The PAC casing is made from galvanized sheet steel (Optional a stainless steel casing is available).

The casing has a corrosion resistant white epoxy spray finish ( RAL 9003).

The drip trays are hinged. PAC will be delivered under little angle, so the condensation always carry away to the drains at one side. Almost all fixing materials are made of stainless steel to prevent corrosion. The end covers can be easily removed for maintenance.
