DESCRIPTION
When a product is manufactured, it is important to check the reliability and durability of that product. Apart from reliability and durability, it is even important to check the usability of that product. For instance, if a product reacts positively to the cold environment, the it is pretty obvious that it is suited for cold environment. But just because it is suited to a cold environment, we cannot go to any arctic place, therefore there are certain products that function according to specific conditions and to meet these conditions test chambers are designed.

Construction
Weiber environmental chambers are double walled convection heated and cooled units. Outer body of our environmental chambers are constructed out of thick PCRC sheet duly pre-treated with primers and rust proofing and painted with long lasting stove enamel or elegantly powder coated. The inner chamber is made of heavy gauge stainless steel sheet of SS-304 grade). The gap between the walls is filled high grade mineral glass wool, which ensures maximum thermal efficiency in our chambers. The unit is provided with two doors, the inner door is made of thick plexi glass/float glass, to view the specimens/culture media/stocks, without disturbing the temperature of the chamber. This door is provided with magnetic door closer. The outer door is made of mild steel sheet lined with stainless steel from inside. www.acmasindia.com

This door is provided with lock and key arrangement. The unit is mounted on a sturdy steel frame. The unit is provided with various customized shelves in various permutations and combinations to suit individual requirements.. The triple walled back of our environmental chambers are provided with two/Four/Six/Eight (size specific) air circulation fans for uniform maintenance of the temperature throughout the chamber.
Heating 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.
CoolingAn energy efficient cooling unit is installed in our environmental chambers to enable bio chemical demand , cyclic and growth studies at lower room temperatures. We use ISI marked high end CFC free compressors of Kirloskar/Tecumseh make, conforming to latest international standards and guidelines.

Humidity Range 10% to 95% (Humidity Applicable as per the Temperature Humidity Graph Attached)
HumidificationA low-pressure droplet free vapor 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.

DehumidificationRefrigeration based de-humidification system is used. The desired level of lower humidity will be achieved by maintaining the precise dew point temperature. The output will automatically be activated based on the set point as well as in ramp up mode after a low temperature cycle.
Humidity SensitivityHumidity is controlled by mean of an electronic humidity controller cum indicator with an accuracy of + 5%
Temperature ControlTemperature range of our standard Chamber is 5o c to 90o c. However we have the capacity to modify the same from -100 to +3000C to suit the individual specialized requirements of our customers.

InsulationThe 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 InsulationGlass mineral wool is one of the most environmentally friendly, stable and sustainable insulants 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 a an excellent thermal insulant. The thickest it is, the best thermal resistance it has, thus reducing heat losses in our equipments for better sensitivity and economical operations. And its impact on the environment in manufacture, use and disposal is minimal.
Air circulationTriple walled back of unit is fitted with two air circulation fans for maintaining tem-perature uniformly throughout the chamber.
