Humidity Cabinet Construction |
|
Outer Panels |
Outer panels
are made of GI coated/ PCRC 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 a 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. 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 |
Single phase / Three Phase based on
requirements. |
