SINGLE-STAGE DRYING SYSTEM
SINGLE-STAGE DRYING SYSTEM
A new drying system from The Conair Group allows users to optimize drying conditions while saving energy.
Built around a Conair Carousel Plus desiccant dryer, the EnergySmart Single-Stage (ES-1) has a TouchView dryer control that adds just enough heat energy to the bed of material in the drying hopper to maintain an optimum temperature profile, resulting in less wasted energy.
For applications involving resins like PET that require precision drying at temperatures as high as 350F (177C), the ES-1 system can deliver an average energy savings of between 35 and 45 per cent compared to conventional dryers.

DRYING SYSTEM REDUCES OPERATING COSTS
The single-flow and dual-flow IntelliPET Drying Systems from Novatec Inc. incorporate PowerGuard Adaptive Control features to cut energy costs by up to 15 per cent over standard wheel dryer designs and up to 50 per cent over old dual-bed designs.
Adaptive Control utilizes three variable-frequency, energy-saving drives: one controls process blower speed, the second controls the regeneration blower and the third controls the rotation speed of the desiccant wheel.
Variable speed drives are also used to improve energy savings in the regeneration process.
The IntelliPET PowerGuard series dryers are designed for two applications. A single-flow hopper/dryer is primarily used for drying virgin/cool PET resin, and a dual-flow dryer and hopper design is used for pre-heated crystallized PET.

PORTABLE CHILLER OFFERS CAPACITY CONTROL
The new Maximum portable water chiller from Advantage Engineering Inc. comes with a Copeland Scroll Digital compressor to provide energy-efficient capacity control of portable and central chillers.
The Advantage M1D microprocessor control instrument is specifically engineered to provide system unloading control. Since there is in compression when the compressor is in the unloaded state, less energy is consumed. Testing shows that compressor energy is reduced by approximately eight per cent when running at 75 per cent capacity, 12 per cent when running at 50 per cent capacity, and 18 per cent when running at 25 per cent capacity.

SHOP FLOOR COOLER FOR MANUFACTURING FACILITIES
A new portable, environmentally friendly cooling fan available from High Command Distributing uses the same amount of electricity as a floor fan but sends out as much cool air as a powerful air conditioning unit.
The fan offers microcomputer-controlled evaporative cooling, and an automatic control device that minimizes energy use. Also, the unit’s small size makes it a good fit for even the tightest shop floor space.
