Spencers Humidity Cabinets, Humidity Test Chambers

Spencers Humidity Cabinets (Model No. : 1190-SHC-001 series)

SPENCERS manufactures custom Humidity Cabinets used by pharmaceutical and biotech industries for a variety of Industrial Testing and Life Science Applications. SPENCERS offers a diverse product line of Controlled Humidity Cabinets designed for high demand testing, processing or conditioning and provides precise environment for products and manufacturing processes.

These humidity cabinets are precision controlled temperature and economically designed to provide accurate temperature and humidity conditions for laboratory testing and/or storage of product. By applying Dew Point and Dry Bulb principals of Psychometrics, a water trough system with stainless steel cooling and heating components allows a simple system to provide excellent stability for short term and/or long-term maintenance free periods of testing. These chambers are often custom/design/build applications unique to a specific requirement.

Humidity Test Chambers provide a controlled environment for a wide range of industrial and biotechnical testing applications. This line is designed to duplicate natural conditions, which allows you to determine the limitations of a sample when exposed to various temperature and moisture fluctuations. Humidity cabinets Water-Jacket Models & Air-Jacket Models Humidity cabinets are available with digital control systems. The humidity cabinets are utilized across various processes such as Shelf Life and Half-Life Testing, Packaging, Sterility Testing, Mil-Specifications, Component Burn-In, Vapor Transmission etc.

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.
Humidity Cabinet 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.
Drainage	It is important that the chamber be connected to a suitable waste drain. Under normal operation only condensate water will dispense from the drain. However in the event of a water supply malfunction, water can flow continually from the drain, due to the safety overflow outlet being connected to the drain outlet.
Castors	Castors for minimal effort mobility.
Humidity Cabinet 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.
Humidity Cabinet 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.
Humidity Cabinet 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, Process cycle settings etc. customized to meet end user requirements.
Power Supply	220 volts, 50Hz / 110 volts, 60Hz .
