ROOM SEALED GAS FIRED UNIT HEATERS
Introduction
LCSA compact gas fired suspended warm
air heaters utilise a tubular heat exchanger
to provide a simple low cost heating
solution suitable for all standard industrial
and commercial heating applications.
LCSA fan-assisted balanced flue units
incorporate an integral flue gas exhaust fan
to induce combustion air mechanically from
outside the building. This same fan then
exhausts the products of combustion back
to the outdoor atmosphere. A single
balanced flue terminal provides a combined
air inlet and flue outlet.
Units are CE certified as either balanced
flue appliances or fan assisted flue units,
where combustion air is drawn from the
heated space.
Each unit is fitted as standard with a high
capacity axial fan and fully adjustable
curved blade horizontal discharge louvres.
Model Range
The LCSA Series gas fired heaters are
available in seven sizes, with heat outputs
ranging from 22kW to 97kW, for use on
natural gas or LPG (to special order).
Features & Benefits
•
High thermal efficiency – above 91% nett,
resulting in lower running costs
•
Multi-try ignition system for
enhanced reliability
•
Dual limit stats for additional safety.
Specification
Heat Exchanger
Tubular aluminised steel heat exchanger
complete with multiple in-shot burners.
Air Distribution
A high capacity axial flow fan is fitted
to all units for improved air distribution.
An optional Economy Thermostat may be
fitted to heaters installed at high level to
recycle warm air down to working level
when the burners are switched off.
The fan operation is controlled by an integral
controller which delays fan start-up until the
heat exchanger has reached operating
temperature and continues to run after the
burner has switched off until all the useful
heat has been dissipated.
Enhanced Safety & Reliability
To ensure safe automatic operation, each
unit is fitted as standard with comprehensive
safety controls. Ignition is controlled and
monitored from a multi-try electronic
sequence controller and gas safety shut-off
valve. A differential pressure switch shuts off
the burners if either the flue or combustion air
supply is obstructed or the flue exhaust
fan fails. A limit thermostat protects the unit
from overheating and a second higher
limit thermostat is fitted to provide dual
safety control.
