Plenum Rated Unit Heater
Series OPH

The OPH series Plenum Rated Unit Heater is ideal for heating the space between the structural ceiling and suspended ceiling. It is also designed to be part of a duct system for central heating. It can be installed both vertically and horizontally (see specifications).

A wide variety of options, sold in kits or factory installed, are available with the OPH series (filters, built-in thermostat, constant torque motor (ECM), etc.)


Our standard corrosion and heat-resistant colors are at the top of the line of today’s paint technology, maintaining that brand new look of your unit for years and years.

For those projects where a specific color is desired, you can choose from our custom color charts and get Ouellet heaters exactly as you want them. We also offer anodizing aluminum products.
