ESCO AIRSTREAM PURE AIR PURIFIER SERIES

Pollens , volatile organic compounds , dust and mold spores that are suspended in the air often cause respiratory problems and allergies . Removal of these pollutants promotes a healthy living environment and reduces related health problems . Esco Airstream PURE Air Purifier provides cleaner air by removing common indoor pollutants through its six-layered filtration system . It delivers rapid air purification and removal of unwanted odours . With its sleek design , it can easily be placed at any part of your office , laboratory , auditorium — indeed a healthy addition to any room .
Features include :
• Smart mode : Wind speed gears are automatically adjusted based on the detected indoor air quality .
• Dual control system : The unit may be operated through :
• Remote control
• Control panel
• A colour-coded LCD screen shows the purifier ’ s basic functions and parameters , easily identifies the status of room air quality .

FULL GAUGE RCK-862 PLUS

Expandable electronic controller of the Rackontrol line , designed for compression centrals for low and medium temperature commercial and industrial refrigeration applications . It controls and monitors saturation pressure and temperature of refrigerant fluid ( 4-20 mA ) or temperature ( NTC ) of a secondary fluid ( Glycol , chilled water , ambient temperature ) through up to six configurable sensors - allowing the use of backup sensors that come into operation automatically in case of need ; and eight digital inputs for monitoring external signals .
It is a product dedicated to the control of condensing units and compression systems with up to three suction lines and three discharge lines , through its eight outputs for compressors or fans , with two analog outputs for proportional control and six digital relay outputs , three of which are solid state that enable the control of variable capacity digital compressors ( VCC ).
The controller features a new control logic intended to minimise the power consumption of the refrigeration system : the progressive algorithm seeks to match the refrigeration demand required by the plant with the power of the compressor set , reducing the number of equipment starts and stops . Through the floating condensation control function , the temperature of the outside environment is monitored to lower the condensation setpoint , thus reducing the system ' s compression ratio and power consumption .
