The OCA series cabinet heater offers a wide range of power ratings, voltage and control options. Most installations benefit from the heater's custom advantages. The cabinet heater can be mounted on the floor, wall or ceiling. It can also be recessed (wall or ceiling) as required. The fans are powered by two-speed motors (Hi/Low option) with permanently lubricated sleeve bearings for many years of trouble-free service. The blower wheel is mounted directly on the motor shafts, which reduces the noise level. No belts or bearing blocks are required for the blowers. Four cabinet sizes are available.
