MKW 400 water cooler

Information

- it is designed for circular piping in connection with EVKA, RMW, RMR units
- the water heater shell is made of galvanized sheet metal
- the condensate drainage pan is aluminum
- the fins are aluminum on copper tubes
- the connection is a threaded clamp transition, not supplied or soldered
- maximum working pressure is 25 bar

Installation and operation
- air velocity in the pipe must not exceed 4 m/s, Otherwise, an additional droplet eliminator must be added after consultation with the EDV technical department
- installation in horizontal position only
- an air filter must be installed in front of the cooler (protection against contamination)
- it is recommended to place the cooler behind the heater
- during installation, it is necessary to remember to drain and fill the system and to provide access for servicing
- as part of the design, the condenser should be designed to take into account the amount of condensate generated
- the condensate drainage with the odour trap should be checked for the possibility of drying out and to ensure sufficient water column height to overcome the pressure drop of the trap
- as a guide, the following can be used to determine the minimum safe level difference in the trap, by taking the total fan pressure Pt in mm of water column, this value is increased by approximately 50 % (the value obtained in this way represents a practical recommended value for the height of the water column in the siphon so that the odour trap cannot be overcome by overpressure blowing or vacuuming by the fan)
- the passing air must be free of solid, fibrous, sticky and aggressive impurities. It must also be free of chemicals that cause corrosion of the materials used i.e. erode aluminium, copper and zinc
- a suitable cooling source can be offered in consultation with the technical department

Caution
The cooler must be installed in a duct route with air flow in the direction of the arrow on the cooler housing. If the condenser is installed backwards, condensate is not drawn into the condenser and flows out of the condenser. For reliable operation of the condenser, frost protection or power control (defrost cycle) must be provided. In the order it is necessary to specify the requirement for the right or left version.
