Hot water air heater unit UHH series

electric powersteamwall-mounted

Overview
Daikin horizontal and vertical cabinet unit heaters (models UHH and UDH) deliver configurable heating for industrial and commercial applications. Horizontal units include adjustable horizontal louvers to modify heat throw and effective mounting height; vertical units discharge downward for high-ceiling or high-mount installations. Optional adjustable vertical louvers combined with horizontal louvers enable full directional control of heated air.

Models

• UHH
• UDH

Complete Directional Control of Air
Vertical units discharge downward to suit high-ceiling areas or locations requiring elevated mounting. When equipped with optional vertical louvers and standard horizontal louvers, the units provide complete directional control of airflow to target occupied or process zones.

Adjust Length of Heat Throw
Horizontal louvers on the air-discharge face are adjustable to lengthen or shorten heat throw and to alter effective mounting height. Four selectable air-distribution devices are available to produce distinct heat-throw and heat-spread patterns to meet specific application requirements.

Fan Operation Controls
Intermittent or continuous fan operation controls are available to match ventilation and heating strategies.
