The EFFEKT boilers are effective heating units that can be used instead of, or together with, old central heating boilers in both small and large facilities and for several special applications. The PK tube boilers are equipped with one 2-inch resistor sleeve and two 2-inch connection sleeves for the heating network. The resistor sleeve can be equipped with one immersion heater with a related control device (maximum output 15 kW). Since new PK boilers are equipped with a separate expansion joint that is placed at the immersion heater end, they can also be installed vertically so that the enclosure of the immersion heater points upwards, as long as venting is taken care of (e.g., with an automatic air vent valve mounted on the expansion joint). The boilers are insulated with polyurethane and cladded with plastic-covered steel plates. The boilers are equipped with immersion heaters and control devices with the required power rating. The immersion heaters and control devices are installed on the boiler at the operating site. The maximum operating pressure of the boilers is 10 bar, and they are made of either boiler steel, stainless steel, or acid-resistant steel. Boiler steel is suitable for the heating of central heating water, whereas stainless steel is suitable for domestic water and acid-resistant steel for special applications.

CONFIGURATION OPTIONS: TY3: 3-pole thermostat and a 3-pole overheat cut-off, TYK: 3-pole thermostat and a 3-pole overheat cut-off, and a 3-pole switch. The operating switch and direct control are available up to the power rating of 9 kW. With higher power ratings, contactor control must be used.

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! Even if no number of products in stock is provided for the product, the delivery time is still only 1-3 business days.***
