Designed for low temperature incubation and routine determination of Bio-Chemical Oxygen Demand (B.O.D.). Double wall construction. Inner chamber made of richly anodized aluminium or highly polished stainless steel sheet with self supports for wide rangeofshelfspacing. Supplied with two/three removeable perforated shelves.

Exterior made out of thick mild steel sheet duly finished in white stoving enable paint or pastle mat finish colour combinations. Outer double wall door is provided with magnetic gasket and lock & key arrangement. Inner door made out of clear acrylic sheet allowing inspection of material in the chamber without disturbing the chamber temperature.

Door operated inner illumination has been provided. The gap between walls of equipment are filled with glass wool for temp. insulation. The cabinet is mounted on castors.

Temperature is controlled by a sensitive thermostat from 5^oC to 50^oC + 1^oC. For lower temp. working a standard cooling unt with a sealed compressor with protective devices has been provided below the chamber for safe and efficient working. Heating arrangement has been made within the chamber for higher temp. working.

The temp. can be regulated within the range by means of a high precision double action thermo regulator. Inner air circulating system is provided to achieve uniform temperature in the whole chamber. A control panel is provided with various indicators, on off switch, L-shaped thermometer. Supplied with cord and plug etc. equipment is workable on 220 V AC 50 Hz single phase.

Inner chamber sizes in mms. Capacity in cft.:

• 610x455x410 (24"x18"x16") 4.00

Humidity and temperature control Cabinet are well designed for conducting different laboratory and research experiments for different quality control tests to be carried out on different materials e.g. cement, motors, various electrical fittings, electronic circuits and components, cloth and paper etc. under controlled temp. and humidity conditions.

 

Construction:

• It is of robust construction. The outer body is made of M.S. Sheet duly pre treated & finished with epoxy powder paint for lasting finish. Caster wheels provided for easy mobility. The intermediate wall is of G.I. Sheet. Inner chamber is made of Stainless Steel/Aluminium Anodized. Tray are also supplied to make the shelves inside the chamber. Inner chamber facilitates self placement at desired height. The chamber is insulated by filling glass wool in the space of between outer body and chamber to prevent temperature loss. Door is also insulated.
• Forced air circulation in the chamber by a blower ensures uniform temperature and humidity inside the chamber. Finned type heater duly insulated from body are provided in the moving air path. Humidity is achieved by generating of steam by immersion type water heater in water reservoir & its subsequent condensation in the circulating air.

 

Temperature and Humidity Control:

• Dry temperature is controlled by reliable imported thermostat from ambient to 55°C ± 0.5°C. Humidity is also controlled by imported thermostat which controls wet temperature for controlling humidity and switches off immersion heaters to stop generating steam. Arrangement exist only for increasing humidity & not for decreasing the humidity.

 

Size of inner chamber(W H D):

• 455 × 710 × 455 mm
• 605 × 605 × 605 mm
• 605 × 910 × 605 mm
