TECHNICAL SPECIFICATION

General Specifications of  Environmental Chambers

Chamber Construction

Bench top / Floor standing / Walk In Environmental Chambers

Capacity

5 Cu. Ft. to 100 Cu. Ft. or walk in environmental chamber as per requirements.

Temperature range

0 °C to +70 °C ( As per requirements)

Humidity range

10% RH  to 95% RH ( As per requirements)

Illumination

Optional Light / Dark control system comprising of fluorescent lights & control system.

Test Cycles

Control system with memory to preset test cycles as per requirements.

Heat / Cool Rates

Heat/Cool rates customized to meet user requirements.

Display

LED/LCD display.

Controller

Microprocessor/Microcontroller based Controller.

Data memory & print

Optional data memory & print interface or added with printer facility.

Alarms

Customized alarm system to warn various parameters.

Environmental Chamber Construction

Outer Panels

Outer panels are made of GI coated/ CPRCA sheet/Stainless Steel

Interior Panels

Interior panels are made of Stainless Steel

Door

Standard hinged door with Double gasket seal between the door and the cabinet increases system efficiency.

Insulation

Polyurethane foam insulation with a thickness of 50mm

Shelves/Trays

Perforated Stainless steel Trays. ( As per requirements). Stainless steel trays lift out for easy cleaning.

Reservoir drain

Recessed Reservoir drain, with convenient drain hose, is easily accessible and a screened based prevents rodent infestation.

Castors

Castors for minimal effort mobility.

Environmental Chamber Heat / Refrigeration system

Heating system

Level, constant heat is continually maintained through a water media, by specially designed high purity magnesium oxide and helically wound nickel-chrome wire heating elements. Elements are totally enclosed for efficient heat transfer and operator safety. The warm air is evenly distributed throughout the chamber through efficient motor fans ensuring very good temperature sensitivity.

Refrigeration  system

SPENCERS superior refrigeration system with optional Backup refrigeration system. Uniform refrigeration is maintained through the use of air-cooled, high torque, hermetically sealed condensing unit. High quality cooling system components include: efficient fan circulation evaporator coil with thermal expansion valve, moisture-liquid indicator, filter drier, heat exchanger, and pressure control valve. All refrigerant lines are copper and fully insulated.

Compressor

Heavy duty Air-cooled compressor. The compressor is distinguished by its excellent performance, low noise level (<60dB) and minimal vibration.

Condenser

Highly efficient condenser with automatic condensate evaporating system.

Evaporator

Internal evaporator system Forced draught.

Refrigerant

Non-CFC/HCFC environmental friendly based on compressor capacity.

Air Circulation

Forced air circulation to maintain chamber uniformity.

Environmental Chamber Air-Humidity Circulation

Humidity System

Unique forced air circulation design maintains an even, continuous, moist airflow throughout the cabinet. Perforated trays further enhance even humidity distribution to testing samples. Self-contained stainless steel water reservoir in each chamber assures a relative humidity of 90%. Temperature variation between trays is ±0.5° C, top to bottom.

Environmental Chamber Control System

Control System Standard

The standard control system consists of Micro-processor based independent temperature controllers for Heat, Cool  & Humidity mode with LED/LCD display. The illumination is controlled through solid state cyclic timer to control the photoperiodic cycle of the chamber. Optional alarm system for various parameters.

Control System Advanced

The advanced control system features robust PID Controllers with process control settings or micro-controller/Micro-processor based Control system. The control system has various optional features such as LED/ LCD Display
Printer Report Program, Data Acquisition Program, Timer, Light control, Adjustable alarm limits, and Process cycle settings etc. customized to meet end user requirements.

Power Supply

220 volts, 50Hz / 110 volts, 60Hz.
