Kontherm KES and KEV series standard unit coolers are configured especially for small and medium coolers and the capacity values are changing from 0,8KW to 60 KW. The specified nominal capacity values are valid for the cooling gas of R404A. In the batteries, aluminium fin having 4, 6, 8, 10 mm fin space and the copper tube of 3/8" and 1/2" are used. All of the batteries are tested at 30 bar pressure and they are all delivered with positive pressure. Maximum operating pressures for these Evaporators are 21 Bar.
Cases of evaporators are manufactured with material of galvanized steel being endurable against the corrosion and electrostatic powder dyed. In our production, RAL 9010 is used as standard color. The side panels and the drainers are designed to be able to removed easily. Intermediate drain pans are used to prevent air by-pass. Depending on the needs, the stainless steel would be used as the material of the cases.
The fans used in the evaporators are Ø300-Ø350-Ø400-Ø450-Ø500 mm in diameter and chosen as ZIEHL-ABEGG or the equivalent. The fans have corrosion resistant blades and have fan protection being in compliance with the safety standards. The permissible working temperature is between -40°C and +50°C and the fans are F thermal group.
