THERMO 2000 VoltMax SCR VOLTSCR20868P3 Commercial Electric Boiler | 67.5 kW - 208V 3 Phase

67.5 kW on 208 V three phase for older buildings that keep their hot-water radiators

The VoltMax 68 at a glance

Thermo 2000 designs the VoltMax SCR for commercial, institutional and multi-unit buildings. The VoltMax 68 model runs on 208 V three phase; its designation rounds the output, which the manufacturer publishes at 67.5 kW, or 230,310 BTU/h. Among the 208 V three-phase sizes we offer in this series, it is the largest.

In Montreal as in Longueuil, former factories turned into lofts, heritage buildings converted into offices and pre-war apartment buildings still heat with hot-water radiators. When their electric boiler needs replacing, the VoltMax 68 can supply that existing network, as well as radiant floors or hydro-air coils added during a renovation.

Period radiators, today’s controls

The setpoint ranges from 50 °F to 200 °F (10 °C to 93 °C). Thanks to the included outdoor sensor, the Schneider Electric controller lowers water temperature in mild weather and raises it when the cold sets in, instead of keeping the radiators scorching all winter. The solid-state relay (SCR) varies output from 0 to 100%, with rotating relay stages; according to Thermo 2000, this modulation limits peak power demand.

The controller shows alarm codes in French or English and, through its Ethernet port, gives access to a web page and sends alarms by email. It also communicates over BACnet IP or MS-TP. Above 60 kW, Thermo 2000 installs a low water cut-off as standard, which adds to the two limit controls and the factory-installed relief valve.

Finding room in the basement

Mechanical rooms in older buildings are rarely spacious. The VoltMax is vertical and compact: Thermo 2000 requires 3 in of clearance on the sides and back, 24 in at the front and 32 in above, and it sits directly on the floor. It weighs 310 lb (141 kg) and holds 11 US gal of water. Four 1 1/2 in male NPT side connections tie it into the existing piping. The circulator and expansion tank are not among the supplied parts; we check whether the existing ones can stay.

On the electrical side, Thermo 2000 publishes a current of 187.7 A for this model, which we compare with the building’s service before confirming the size.

What AirGreen does

We start with a free on-site estimate: radiators, piping, air vents, mechanical room, electrical service. You then receive a detailed written quote. On installation day, our technicians remove the old unit, install the VoltMax, connect it to the network, make the electrical connection and mount the outdoor sensor. They fill and purge the system, then set the heating curve to suit the radiators.

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.
