Supported Technologies

Supported technologies include but are or limited to the following systems:

Motor drive systems

Compressed air

• variable speed drives to replace modulating or load/unload operation;
• compressor sequencing controls;
• dew point controls on desiccant dryers;
• two stage air compressors;
• cycling or thermal mass dryers;
• receiver tanks;
• flow controllers;
• heat recovery for space or process water preheating;
• eliminating poor end uses such as open blowing;
• end use pressure reduction.

Pumps

• variable speed drives to replace control valves for flow control;
• match pump and system requirements to operate at best efficiency point;
• elimination of recirculation or bypass loops;
• minimize pressure losses with larger pipe sizes;
• end use pressure reduction.

Fans/Blowers

• variable speed drives to replace outlet damper control for flow control;
• match fan and system requirements to operate at best efficiency point;
• eliminate restrictive ductwork fittings and at fan inlet and outlet.

Industrial refrigeration systems

• variable speed drives for compressors, evaporators and condenser fans;
• control upgrades to optimize operation of compressors, evaporators and condensers;
• floating head pressure control;
• oversized condensers;
• thermo siphon oil cooling;
• purgers for non-condensables;
• recover heat from refrigerant vapour leaving compressor;
• end use temperature increases.

Energy management systems

• control demand by turning equipment off or resetting process control points.
