Complete Solution for Environmental Stimulation.

Introduction

Deep Freezers / Ultra Deep Freezers ,Temperature, Cooling.

It is constructed in compliance with IEC, IS 9000.

Deep Freezers

Deep Freezers / Ultra Deep Freezers is intended for performing different type of test where the temperature of sample environment must be controlled within certain limits. The role of environment testing into examine and prove the suitability, reliability, durability of products through the exposure to the environmental effects of temperature, Acceleration of the environmental effects that these products will experience in nature is required. Deep Freezers / Ultra Deep Freezers is intended for performing different type of test where the temperature of sample environment must be controlled within certain limits.

Deep Freezers / Ultra Deep Freezers-85°C Ultra-low Temperature Freezers are developed for reliable storage conditions of research samples for laboratories, hospitals, repositories and more. Through research and development, a new focus has been placed on our refrigeration system, controls, alarms/monitoring, ergonomics, construction and energy efficient operation to make our freezers the reliable solution for long-term storage of cancer cells, stem cells, cord blood, T-cells, organ/tissue and other samples.

Our policy of continual liaison with leading researchers ensures we maintain our premier position as suppliers of high quality Deep Freezers / Ultra Deep Freezers and associated facilities. Our Deep Freezers / Ultra Deep Freezers , were designed with Safety, Reliability, Ease of operating and Ergonomically.

Main Features

Deep Freezers

Test space dimensions are 100 litres to 2,000 litres. Temperature Ranges – 75° C to RT +5° C. Temperature deviation +/-0.5° C to 1° C. Temperature Resolution 0.1° C. Temperature Gradient +/- 1° C to 2 ° C.

Construction

Deep Freezers

Interior structure made of non frost vapour / air tight type. The high - gloss polished stainless steel test space is welded vapour tight, has well finished edges. it remains impervious to corrosion and easy to clean. Interior structure made of non frost vapour / air tight type. 18 SWG 304 grade stainless Steel / GI / Plastic type with adjustable / removable shelving. Outer external structure made of 16 Or 18 SWG CRCA /GI/ Stainless steel with electrostatic powder super fine coating finishing for a good appearance.

Insulation is environmentally friendly free of asbestos and CFC free high strength foamed in place PUF insulation guarantees the best possible insulation values and hence, it will decrease the operating costs.

Door hinges fitted on the right hand side Or on top side of the chamber with front opening Or top opening single door or Multi doors. Multi-point gasket seal system ensures a tight seal. Double lined ‘A’ grade silicon gasket on door as well as chamber body so that like proof tightens the door for better performance with multi pan glass viewing window. Defogger heaters provided with an auto cut – off as well as suitable illumination provided to view the specimen under test. Easy-In / Easy-Out door latch for one-handed operation, positive seal against gasket.

Performance

Deep Freezers

Water Cooled / Air-cooled mechanical type single stage non CFC refrigeration system / mechanical type cascade compression refrigeration system. Ozone friendly refrigerant with hermetically sealed / semi sealed compressor provided and system is designed such a way that, safety protection against high / low pressure and temperature. Electronic auto expansion valve system for expansion mechanism. Water / Air cooled condenser.

Plate fin type cooler. Refrigerant R404A / R23 / R 508. Pressure measuring device provided for measuring suction and head / discharge pressure of refrigeration systems. HP / LP cutoff / Oil separators with oil return system.

A cascade refrigeration system that utilises dual compressors offers a quicker, more reliable way to control storage conditions. Quicker temperature recovery after door openings. Insulated inner doors help maintain interior temperature. Commercially available HFC refrigerants are highly efficient, environmentally safe and non-ozone depleting

Instrumentation System

Programmable controller using large screen display. Instrumentation package features flexible. Other functions are included user friendly operation with TFT LCD touch screen as well as key input, graphical display of program patterns, testing history trend grapes. A no. of programs & profile segments with ramp & soak duration provided for cyclic operation. Password proaction system.

The controller is able to communicate with many different types of hardware using high speed RS 232/485 communications ports and USB communications for fast downloads. Power failure recovery operation. Compressor start - up delay sequence delays re - start after building power failure.

Microprocessor PID non programmable type controller in RE models.

P.T 100 sensor is measuring the temperature of the chamber.

Safety Devices

Deep Freezer / Ultra Deep Freezer equipped with an emergency stop switch. High reliability and operator safety. Easy protection of chamber and specimen in case of failure. Chambers stop if the door is opening as operator safety. European style design signal tower.

Control circuit over current protection. Thermal fuse. Adjustable adequate safety cut – out against high and low temperatures. Chamber door limit switch. Every electrical functional circuit is equipped its own safety facility which shuts down the functional circuit affected or the entire test chamber in case of a malfunction.

Utility

Cable Port holes are located on the left or on the right side of the test chamber and shall be used for inserting measurement and control cables, other supply connections or additional equipment with rubber plug.

Standard specification shelves and shelf are added as required.

Drain pipe with suitable fittings

Electrical connection: 415 / 220 V AC +/- 10%, 3 / 1 phase/N/PE.50 Hz.
