CoDeSys (Controller Development System) software technology
Indirect heating system is provided in our units, comprising of air heaters made of high grade Kanthal A-1 wires of suitable wattage. The warm air is evenly distributed throughout the chamber through efficient motor fans ensuring very good temperature sensitivity.
An energy efficient cooling unit is installed in our photostabilitytest chambers to enable studies at lower room temperatures. We use high end CFC free compressors of Kirloskar/Tecumseh / Bitzer/ Denfos make, conforming to latest international standards and guidelines.
DETAILED DESCRIPTION ALONG WITH SALIENT FEATURES ARE AS UNDER FOR REFRIGERATION MACHINE
Air-cooled condenser is internally grooved finned copper tubes used for high heat transfer area, which not only reduce power consumption, but also bring down the condensation faster. This unit is designed. &verdigris& reduces the resistance, saves energy consumption and ensure good heat exchange.
- HERMETIC COMPRESSOR
Single stage Reciprocating Compressor. Give the High Efficiency compared to sealed compressors, Less Power Consumption , Accessible for repairing, low noise level, Less Vibrations, Wide Voltage Range, Designed for Extremely High Ambient ,Full warranty etc
- COOLING SYSTEM
The compressor is mounted perfectly to ensure recommended level of sound and vibration.
- Low and High Pressure switch of RANCO/Danfoss
Which ensures the compressor and refrigeration system when low pressure will occurs it trip off the compressor. This is the only operator friendly switch can easily reset.
- Hand Shut off Valve
Is the only Condensing Unit, which is equipped with it. This valve is used for pump down the total gas in to the condenser & receiver in the faulty condition.
- Liquid Dryer of Danfoss make
Which is equipped in the liquid line for ministration of moisture in the liquid. It will collect all the moisture in side the refrigeration line as well as gas.
- Moisture Indicator of Danfoss make
The sight glass area in the Moisture Indicator shows at a glance the condition of the refrigerant system. The moisture indicator element changes colour and indicate if the system is safely dry, or dangerously wet.
- Solenoid Valve of Castle make
In most refrigeration applications, in order to automatically control the flow of fluids in a system, it is necessary to be able to start or stop the flow in the refrigerant circuit. An electrically operated solenoid valve is usually used for this purpose. Its basic function is the same as a manually operated shutoff valve, but it can be positioned in remote locations, and may be conveniently controlled by simple electrical switches.
- Oil Separator of Stainless Steel 304
The oil separator intercepts the oil mixed with compressed gas and returns it into the crankcase of the compressor, thus assuring an efficient lubrication of its moving parts. Also, it improves the overall efficiency in the system.
- Suction Accumulator
Maximum Efficiency of the relief device (expansion valve) because it is supplied with sub cooled Liquid.
- Liquid Receiver
As per ASME Section VIII Division I for storage of refrigerant.
20% to 85%RH
Humidification (WATER TANK AND AEROSOL SYSTEM)
A low-pressure droplet free vapour boiler using direct vaporization system is used. Water Reservoir is provided at the side of the chamber with a 10 x 8mm PU tube quick connector and water level is automatically controlled through a water-in solenoid valve. The wick tank water level is automatically maintained through a water solenoid valve and an electrical float switch. The de-mineralized water or single distilled water supply to the humidity inlet having a resistance measurement of approximately 50,000 – 200,000 Ohm/cm is provided with the unit
Aerosol Generator and Monitor is a multi-function aerosol instrument comprised of an atomizer aerosol generator. As an aerosol generator can be used to generate a monodisperse aerosol by atomization. The output aerosol concentration is continuously monitored by control facility to provide a stable aerosol output with a known particle size and a known aerosol concentration from 10nm to1000nm. Water Reservoir is provided at the side of the chamber with a 10 x 8mm PU tube quick connector and water level is automatically controlled through a water-in solenoid valve. The wick tank water level is automatically maintained through a water solenoid valve and an electrical float switch. The de-mineralized water or single distilled water supply to the humidity inlet having a resistance measurement of approximately 50,000 – 200,000 Ohm/cm is provided with the unit.<
- Dehumidification: Refrigeration based de-humidification system is used. The desired level of lower humidity will be achieved by maintaining the precise dew point temperature. If you need more low humidity than the standard range then refrigeration based dehumidification system can be incorporated on customer’s request.
- Humidity Sensitivity: Humidity is controlled by mean of an electronic humidity controller cum indicator with an accuracy of ±3%RH
- Temperature Control: The temperature inside our temperature and humidity controltest chambers is controlled through Nano technology based HMI & PLC controller.
- Temperature Range: Temperature range of our standard Chamber is -2°C to +40°C. . However we have the capacity to modify the same to suit the individual specialized requirements of our customers.
- Temperature Sensitivity: Temperature inside our Temperature And Humidity Control test chambers are controlled with a sensitivity of + 0.3 o C or better.
- Illumination: OurTemperature and Humidity Control test chambersare provided with door operated illumination system comprising of fluorescent lights, beside two panels of diffused fluorescent light panel located at the either side of the chamber to enable the user to conduct the photo periodic tests and experiments.
- Insulation: The gap of 75 mm between the outer and the inner wall is filled with special grade glass wool to prevent thermal losses.
- Mineral Glass Wool Insulation: Glass mineral wool is one of the most environmentally friendly, stable and sustainable insulates available. Glass wool is incombustible by nature. Euro class classification is A. It does not propagate flames and toxic smokes. Thanks to a dense entanglement of materials with a low conduction and trapping a great amount of air, glass wool is an excellent thermal insulant. The thickest it is, the best thermal resistance it has, thus reducing heat losses in our equipment’s for better sensitivity and economical operations. And its impact on the environment in manufacture, use and disposal is minimal.
- Air Circulation: Triple walled back of unit is fitted with two air circulation fans for maintaining temperature uniformly throughout the chamber
