THERMO 2000 VoltMax SCR VOLTSCR600132P3 Commercial Electric Boiler | 132 kW - 600V 3 Phase

132 kW, modulated from 0 to 100%, to heat a building on 600 V power

A commercial boiler for buildings with a hot-water loop

The VoltMax SCR 132 is Thermo 2000’s 132 kW commercial electric boiler, in its 600 V three-phase version. The manufacturer rates it at 450,384 BTU/h and places it in its configuration B, which runs from 99 to 180 kW. Its name comes from its modulation: solid-state relays (SCR) vary the output from 0 to 100%, alongside relay stages.

It is meant for managers of apartment buildings, condominium boards and owners of commercial or institutional buildings heated with hot water: hot-water baseboards, radiators, radiant floors or hydro-air coils. It can also supply an indirect water heater, thanks to the second setpoint built into its controller.

Its place in a Quebec building

Many Quebec buildings receive 600 V three-phase power. On that service, the VoltMax SCR 132 draws 127 A. Rather than switching full blocks of power on and off, it adjusts its output to the building’s demand; Thermo 2000 points out that this modulation limits peak power demand. The supplied outdoor sensor lets the controller lower the water temperature on mild days and raise it when the cold sets in.

Take an apartment building in Montreal whose old boiler sits in a corner of the mechanical room. The VoltMax is vertical and needs only 3 in of clearance on the sides and back, 24 in in front and 32 in above. It holds 30 US gal of water, connects through four 2 1/2 in NPT side connections and accepts a setpoint from 50 °F to 200 °F. At 550 lb (250 kg), its delivery takes some preparation: access, stairs, dolly.

What AirGreen’s installation covers

We start with a free on-site estimate: electrical service, condition of the loop, existing emitters and available space. You then receive a written quote that names the boiler and everything that goes with it. The circulating pump and the expansion tank are not on Thermo 2000’s list of supplied items; we size them for your system.

On installation day, our crews set the boiler in place, connect the piping and the 600 V supply, fill and purge the loop, then set up the Schneider Electric controller and the outdoor reset curve. If the building has a management system, the boiler can be linked to it through BACnet IP or MS-TP. Thermo 2000 warrants the tank for 10 years (limited warranty, closed-loop heating) and the electrical and mechanical components for 2 years.

AirGreen is a family business established in Montreal for more than fifteen years, holding RBQ licence 5645-9605-01 in ventilation, refrigeration and electrical work. That is why we handle the boiler’s electrical connection ourselves.
