Spirec KNV-0 spiral coil cylindrical heat exchanger 32 kW wi

Spiral coil heat exchanger 32kW stainless

KNV heat exchanger series general information:

very small size and space requirement
excellent heat transforming ability
it also heats a very small amount of liquid
suitable for a wide range of hot water production, heating separation, underfloor heating service, cooling processes
all parts of the heat exchanger in contact with the moving liquid are made of 0.5 mm corrosion-resistant steel
AWI welding
silicone seal

What are the advantages of our Spirec heat exchangers compared to a plate heat exchanger?

NO,- or it is VERY DIFFICULT to clog, because there is no scale deposit, or an insignificant amount
MULTIPLE lifetime compared to conventional heat exchangers
Suitable for heat exchange of WATER, OIL, STEAM, GLYCOL media
CAN BE CLEANED due to the use of acid-resistant stainless materials
suitable for floor heating systems without a control unit

Spirec KNV-0

The KNV type heat exchangers, following the KN series, have very goodproperties. They are welded together from completely corrosion-resistant elements. In terms of its dimensions, its design is smaller than the KN series. It has a smallspace requirement and, thanks to the thin-plate design, verygood heat-transforming capabilities in a wide range of pressure conditions span>applicable. With its small size and hydraulic properties, it fits well with today's heating devices. The forward heating water of the heater must be entered from the heat exchange into the jacket side. The heat exchanger completely separates the primary and secondary sides, its application enables the creation of a mixed heating system.
