Overhead Infrared Heaters
Aitken's OH series heaters install just like fluorescent lighting fixtures — suspended overhead to focus heat exactly where it's needed. Use them individually, in pairs to heat one area, or in a group to heat an entire building.

Danger — Hazard of Fire: Infrared radiant heaters must not be operated where combustible materials, flammable gases, vapors, or corrosives are present.

Common Applications
What Aitken Overhead Heaters Are Used For
Warehouse Aisles
Narrow aisle heating between racking, where full-building heat would be wasteful.
Large Repair Facilities
Localized heat over bays and work areas in large plants and shops.
Car Washes
Weatherproof construction stands up to wash-bay moisture and washdown cleaning.
