Walk-In-Humidity (Stability) Chambers

• Temperature & Humidity Suitable for 25 °C& 60% RH, 40 °C & 75% RH, 30 °C & 65% RH
• Specially designed chambers to carry out stability studies at low humidity conditions such as 25°C & 40% RH, 40°C & 25% RH NMT, 30°C & 35% RH

Construction :
 

This unit has double walled insulated PUF modular panels which can be easily assembled at site. Interior is made of Stainless Steel and Exterior is either made of Mild Steel finished with powder coating or Stainless Steel. The unit has full-length inner glass door and outside metal door with magnetic gasket and lock. The unit is provided with perforated Stainless Steel trays. Forced air circulation for uniform temperature.

Intelligent Control System :

The controlling system having is PLC Base and PC communication

Heating System :

Long lasting stainless steel tubular heaters with s.s. fins.

Humidity System :

Humidity is by steam injection. A humidifier tank is fitted with two nos of heaters. One heater works as a stand by in case the regular heater fails. A water reservoir tank is connected to the boiler tank. Two boiler tanks are fitted with magnetic float switch and float valve. Magnetic float switch is provided for the safety of boiler as it facilitates in cutting off the heater supply in case of low level of water.

Senesor :

Rotronic make temperature and humidity transmitter 4-20mA with very low drift per year. Temperature in degree Celsius and Humidity in %RH with 0.1°C and 0.1%RH resolution.

Cooling System :

Hermitically sealed compressor coupled with evaporation coil and condenser, safe guarded by time delay circuit. CFC free refrigerant.

Alarms :

Audio and visual alarms are generated for temperature / humidity variation

Safety :

This unit is provided with safety devices for temperature and humidity over shoot in case of malfunction’s

Standby Sensor :

When controlling sensor fails it automatically switch over to standby sensor.
The unit works on 230 Volts AC and 50Hz mains supply.
 

Optionals :

• Common Software: Chambers are connected on TCP/IP (Ethernet) with the centralized work station and transferring data in database. This centralized workstation provides the tool for viewing, trending and alarm management of chambers. It has date and time stamp audit trails and complies to US FDA 21 CFR Part 11.
• Temperature and Humidity Scanner: 8 point scanner for temperature and humidity having 8 temperature and 8 humidity probes provided with alarms to monitor various parts of equipment.
• Stand by Cooling System (Auto Switch Over): A fully functional cooling system can be provided as standby. It comes in operation automatically when the regular system fails to function.
• Door Access System with Touch Screen Display: The door access system restricts access to the chamber to authorized persons only. In this system a physical lock is provided additional to this password access control is provided. Maximum six users can access the chamber.
• Remote Alarm System: Alarm for Temperature & Humidity deviations. Indicator LED to identify equipment deviation. Alarm hooter test push button
• Mobile Alert System Suitable for Equipments whenever the alarm is generated by the system the user has to acknowledge the alarm with in predetermined time. If the user fails to acknowledge the alarm will send as a sms to 6 predefined numbers
