THERMO 2000 VoltMax SCR VOLTSCR20834P3 Commercial Electric Boiler | 34 kW - 208V 3 Phase

A 34 kW electric boiler that adjusts its output from 0 to 100% for buildings on 208 V three phase

The VoltMax 34 and the buildings it heats

Thermo 2000’s VoltMax is a hot water electric boiler designed for commercial and institutional buildings. The series covers 22.5 to 180 kW, single phase or three phase, from 208 to 600 V. The 34 kW model belongs to configuration A, which groups the 22.5 to 90 kW sizes. On a 208 V three-phase supply, it produces 116,008 BTU/h and draws 93.9 A.

It suits buildings heated with water: a small office building, a neighbourhood store, an apartment building whose radiators or radiant floors are connected to a central loop. It can also feed the hot water coils of a ventilation system (hydro-air) and, thanks to its controller’s second setpoint, an indirect water heater.

Output that follows the building’s demand

What sets the SCR series apart is its modulation. Solid-state relays vary the output from 0 to 100%, in addition to relay stages. Instead of jumping from one whole element to the next, the boiler supplies the heat the building needs at that moment. Thermo 2000 points out that this approach limits peak power demand. The controller also rotates the stages to share the work among the elements.

The outdoor sensor is included. The Schneider Electric controller uses it to adjust the water temperature to the weather: cooler water in mild weather, hotter water during cold snaps, within a 50 °F to 200 °F setpoint range. Its 3 in backlit LCD shows alarm codes in French or English, in °C or °F.

For building managers, the controller communicates over BACnet IP or MS-TP, accepts an external 0-10 Vdc signal for setpoint and output, and offers a web page and email alarms through its Ethernet port.

What installation by AirGreen covers

We start with a free on-site estimate in Montreal, Laval, Longueuil, on the North Shore or on the South Shore. We look at the 208 V three-phase service, the mechanical room and the existing hot water loop. You then receive a written quote that specifies the circulator and expansion tank to plan for, since they are not among the parts supplied by the manufacturer.

On installation day, we position the boiler with the required clearances: 24 in in front, 32 in above, 3 in on the sides and at the back. We connect it to the loop through its 1 1/2 in NPT connections, pipe the relief valve discharge, mount the outdoor sensor and make the electrical connection. After filling and purging, we program the controller and check the modulation with you.

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