LCSA Series

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.
