Actively monitors the load current, reacting to changes in load almost instananeously, while returning the true power factor to near unity. This dual duty product accomplishes both objectives immediately upon installation without the need for a special commissioning process. The filter's ability to adjust to a dynamic load also means that an expensive harmonic study is not necessary prior to the installation of an H5. The ease of installation plus the superior performance of this filter makes the H5 the ultimate choice in harmonic mitigation solutions.

Interact Power's small low amperage line conditioner may be used with any microprocessor-based electronic equipment. With a low-impedance isolation transformer, you can trust these conditioners to protect your sensitive equipment from the biggest problem for today's computers: commonmode voltage, which can cause everything from equipment lock-ups to data losses and more.

These models also feature surge diverters and power line filters to eliminate noise, spikes and transients before they have a chance to damage your equipment or your data. They are suitable for use with instrumentation, analyzers, desktop PCs, LANs, communications systems and telephone systems that draw up to 1 Amp. Contact the factory for information on higher current rated, different voltage or different receptacle configuration line conditioners.

PGC's 1500-3000 CFM system is a durable, high quality piece of humidity/temperature conditioning equipment for scientists and engineers whose research, testing, or quality control applications require environmental testing and simulation within extremely narrow tolerances.

PGC conditioners are two-temperature generators. Within the unit, a water spray temperature and a leaving air temperature are precisely controlled. A portion of the air always passes through a water spray where it is cooled to the temperature of the water and saturated. The air is then reheated to the desired dry-bulb temperature and returned to the conditioned area. The temperature of the water spray will approach the dew point of the process air. By controlling dew point temperature and dry-bulb temperature, a very constant relative humidity is maintained.

If the area to be conditioned has changing internal loads or requires make-up air, the Cascade System should be selected. This system adds a humidity sensor to the control loop that will reset the water spray temperature to compensate for load changes.

Air Flow

Air returning from the conditioned space passes through a return duct and, depending on the position of the face and by-pass damper, a portion is directed through a water spray and the balance by-passes the spray. The portion of the air subjected to the sprayed coil is cooled to within approximately 1.0ºC of the spray water temperature. This essentially saturated air passes through a mist eliminator and mixes with air that by-passed the sprayed coil. The mixed air is forced across an electric air heater by a fan. The conditioned air is then supplied, via ductwork, to the work or test area.

Air Control

A proportioning control system compares the dry-bulb temperature, measured by an RTD, to the air temperature set point. A pulsed output, which is ordinarily "on" 50% of the time when stabilized, is supplied to the air heater control circuit. A second analog output positions the by-pass damper so that the amount of air by-passed is directly proportional to the percentage of air heat applied. If the air temperature drops below the selected set point, the controller calls for more heat; i.e., the "on" time of the heater increases. The face and by-pass damper begins to compensate so that more returning air by-passes the spray coil, returning the pulsed output to the normal 50% "on" condition. Conversely, if the air temperature increases above the set point, the heater is pulsed less and more air is directed through the spray chamber.

Water Control

A platinum RTD in the water line supplies feedback to the proportioning controller, the output of which adjusts a refrigeration valve and a water heater. Water spray temperature is controlled within ±0.1ºC.

Relative Humidity Control (Cascade)

The desired relative humidity is set to within ±0.1%. The proportioning controller receives a feedback signal from a relative humidity sensor and, if necessary, causes the water temperature set point to be changed. The output of the RH controller, like that of the air temperature controller, is normally "on" 50% of the time; i.e., time on equals time off. If the relative humidity drops by as little as 0.2%, the "on" time of the controller will increase and reset the water temperature higher by approximately 0.1ºC. This will, in turn, increase the relative humidity to the selected set point, returning the controller output to a 50% duty cycle.
