Water heaters 15-48 kW

The PPK tube boilers are equipped with four 2‘‘ resistor sleeves and two 2‘‘ connection sleeves for the heating network and one 1‘‘ expansion joint. The necessary number of resistors (depends on the power requirement) can be installed in the resistor sleeves (P) up to the combined power rating of 48 kW.

For control, a thermostat, an overheat cut-off, or a combination of these can be installed on one or more immersion heaters. Standard configuration requires that one immersion heater is equipped with a TY3 control unit that controls all of the resistors with the aid of contactors. Each immersion heater can also be equipped with a similar unit, in which case the contactors become unnecessary and various freely selectable temperature steps are created. With the TY3 thermostat, a maximum power of 9 kW can be controlled directly (e.g., PPK 364, 4x9 kW).

Due to their small size and light weight, the PPK boilers can, alike the PK boilers, be installed directly to the pipe system without wall or floor mounting.

The boilers are made of boiler steel, stainless steel, or acid-resistant steel. Boiler steel is suitable for the heating of central heating water. Stainless steel, on the other hand, is suitable for domestic water and acid-resistant steel is suitable for special applications. The prices in the table have been calculated for a boiler that is made of boiler steel and equipped with stainless-steel resistors. The maximum operating pressure is 4 bar. The boilers made of stainless or boiler steel are manufactured to withstand a maximum operating pressure of 10 bar, and they are available upon request.

Warning!

The boilers must be installed in a manner that ensures that no air pockets are created around the immersion heaters under any circumstances. The immersion heaters cannot withstand even brief periods of dry operation.

***NOTE! The delivery time for the tube boilers is 4–6 viikkoa***
