Model 5/25

Suitable for ceiling heights up to 5m in height from fl oor to ceiling, such as Sports Halls, Assembly Halls, and small Warehouses. Draws just 25 Watts in electric power and provides a volume fl ow rate of 126 l/s or 7.6m3/min. Can be suspended from any suitable point at the underside of roof level through the adjustable arm and supplied with a standard 3m lead to plug into any suitable power supply. Since the weight of the system is just 4.5kgs, no special supports are required. All Heat­Harvesters™ are supplied as standard in grey but other colours can be supplied to Special Order.

Model 8/35

Suitable for large buildings with a floor to ceiling height of up to 8m in height and probably the most popular Heat‑Harvester™ model. It draws just 35 Watts in mains power and provides a volume fl ow rate of 150 l/s or 9m3/min and is ideally suspended in the middle of each bay at approx 8m – 10m centres, depending on the building layout. For warehousing, where racking is involved, the Heat‑Harvester™ should be suspended over the central walkways rather than over the racking itself, so as to benefi t from the 8m column of air movement. All Heat‑Harvester™ systems are almost silent in operation and are therefore ideally suited to Assembly Halls, Churches, and Community Halls, where complete silence is often required. Running costs are less than 10p per day.

Model 12/75

Suitable for buildings with a fl oor to ceiling height of up to 12m in height, this model is fi tted with a 75 Watt
motor for maximum power and provides a volume flow rate of 238 l/s or 14.3m3/min. This is the largest Heat‑Harvester™ model and is ideal for large Warehouses, Aircraft Hangars, and Storage Buildings, where the wasted heat must be considerable. The heat is required at the occupied level but inevitably, heat rises and therefore the temperature at the underside of roof level can easily be 4°C – 5°C higher than at fl oor level and this high level heat is totally wasted.

Suspended Ceiling Model

All three Models are also available for suspended ceilings, where simply, a standard ceiling tile is removed and the Heat‑Harvester™ then drops into position. Electrical connections should be made in the normal way.

By harvesting this wasted heat and forcing it back down to floor level, not only can temperature thermostat settings be reduced but the workforce will find working conditions far more pleasant and enjoy year round temperatures typically around 20°C. And yet, the cost of running the Heat‑Harvester™ largest model is still less than 25p per day.
