Model SG7500
High Flow Electric Heater for Nonflammable Gases

SG7500 HeaterModel SG7500 Electric Heaters are designed for use with nonflammable liquefied compressed gases to prevent regulator freeze-up and to assure uniform temperature under high flow conditions. Connected between the cylinder valve and a suitable regulator, the thermostatically controlled heater warms the gas stream allowing for flow rates up to 1000 scfh* (CO2) without regulator freeze-up.

The heater is designed with a dry heat exchange medium made of aluminum and continuous high pressure stainless steel tubing with no internal joints.

Standard Features
  • Heavily Insulated Cabinet remains "cool".
  • Flow can be in either direction without loss of efficiency.
  • Mounting Bracket provides for convenient, wall mount installation.
  • Heater can be left on indefinitely, even under no-flow conditions, without resultant damage.
  • C.S.A. Approved
Optional Features
  • Manifold Adapter Block provides a means to install heater between gas cylinder and regulator with CGA connections.
