THERMO 2000 VoltMax SCR VOLTSCR24060P3 Commercial Electric Boiler | 60 kW - 240V 3 Phase

Heating and hot water for a busy building, with a single 60 kW electric boiler on 240 V three phase

One boiler for two needs

In a seniors’ residence, an inn or a small hotel, occupants shower at all hours and expect steady heat. Thermo 2000’s VoltMax 60 meets both needs. This commercial electric boiler delivers 60 kW, or 204,720 BTU/h, on 240 V three phase, to the water loop that feeds the building’s radiators, radiant floors or hydro-air coils.

The controller also provides a second setpoint for an indirect water heater. Domestic water is heated there by the boiler water, and the pump contact works with or without domestic hot water priority, depending on the setting we choose together.

Precise control of both circuits

The heating loop follows the weather thanks to the included outdoor sensor: water temperature rises in deep cold and comes back down in mild weather, within a setpoint range of 50 °F to 200 °F (10 °C to 93 °C). The solid-state relay (SCR) varies output from 0 to 100%, and, according to Thermo 2000, this modulation limits peak power demand.

The Schneider Electric controller shows its alarm codes in French or English on a 3 in backlit display. For evening or night staff, the Ethernet port gives access to a web page and sends alarms by email; a building management system can also reach it over BACnet IP or MS-TP.

In the mechanical room

Thermo 2000 publishes a current of 144.3 A for this model on 240 V three phase. The boiler is vertical and compact, with 3 in of clearance on the sides and back, 24 in at the front and 32 in above. It weighs 310 lb (141 kg), holds 11 US gal of water and can sit on the floor. Four 1 1/2 in male NPT side connections tie it into the loop; the relief valve and drain are 3/4 in female NPT.

The indirect water heater, circulator and expansion tank are purchased separately. The low water cut-off is optional at 60 kW.

AirGreen’s installation

Our on-site estimate is free. We look at the heating loop, the current hot water production, the electrical service and the mechanical room. The written quote that follows details the boiler and everything that goes with it. Our technicians then install the VoltMax, connect it to the loop and the indirect water heater, make the electrical connection, mount the outdoor sensor, fill and purge the system, then set both setpoints. We schedule the work to keep the interruption of the occupants’ heat and hot water to a minimum.

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. Thermo 2000 covers the tank for 10 years (limited warranty, closed-loop heating) and the electrical and mechanical components for 2 years.
