Salt Spray Chamber ASTM Model (FRP)
Model No : SRL / SC-54
Standard : ASTM B117
Applications :
These chambers are used to study the deterioration in painted films when put under exposure to salt solution & to test the corrosion resistence of protective coating of on ferrous non ferrous material. This apparatus consists of perspex chemically inert container (Acrylic) with a close fitting cover in which a fine mist of the spray solution is produces through an atomizer.
Ecocentric System :
Chamber runs on the basis of Dewpoint control. Less deviations during short-term door opening & power failure. Less utility area Increased storage area. Low operating cost. Minimum power & water consumption. Reduced deviations. Less breakdowns due to standby refrigeration & humidification system. Due to PLC HMI & controlling through microprocessor based PID Temp. & RH operations the on time of both Temp. & RH system is reduced & efficiency of this system is increased with reduced energy consumption.

For Known period of time & then decreased back to initial temp, in fixed time internal gradually. Stepwise Programmable Controller with 10 or more programs Provides Automatic Operation of Variable Temperature & Humidity Value, 50 Or More Cycles With Minimum 100 Sections in Each Cycle, for E.g. the temp. shall rise gradually as 32.1,32.2…. to the desired temp by the end of set time. Data logger with RS 485/232 port for logging & transfer of data. Auto restart, power failure event logging. Technical Design and Construction Silent Fan Motor to Maintain Uniform Temperature and Humidity. Data collected from each logger shall be transferred to central data storage unit. Shall provide central data storage unit with facility to retrieve the stared data at any time. Multiple programs linked together to simulate natural condition. Control system shall have audio/audiovisual warning/alarm when set temperature/RH is below or above the set values. Ethernet communication port ambient temp. monitoring. Alert Unexpected Interruption of Electrical Power or Unauthorized Change. 4 digit password lock.
Refrigeration system : (Air Cooled)
Emerson /Danfoss/Tecumseh: make compressors, 1 stage cooling system for TEMP. & Humidity Control. All accessories such as HPCO/LPCO, Oil Separators, Dryers, Relays, OLP etc. of
Danfoss/Tecumseh Emerson Make. CFC free refrigerant to be used to comply with the New Environmental Regulation. Will have suitable tonnage compressor for maintain temperature with lights on. Will have hermetically sealed condensing unit compressor coupled with Evaporation coil and condenser, safe guarded by time delay circuit. Cabinet shall be supplied with air-cooled condensing unit with extended compressor life and close temperature control. Cooling system will be split type to place condenser unit in a ventilated area to avoid hot air in growth chamber. Cooled air shall be delivered in such a way to reduce or eliminate condensation within media dishes and to provide maximum uniformity In different research vessels. This may be through silent and durable fan motors or through any kind of advanced air diffusers. Air Cooled Condenser with solenoid & LP to pass hot gas to the chamber for uniformity & long life of compressor for continuous usage. Phenolic coating for cooling & condensing coils (All weather proof).
Humidity Range :

Construction :
The Chamber will be mono block construction that comprise all system necessary for operation. The internal & External made of non-corrossive FRP. The Insulation material will be low k factor, high density and non Hygroscopic nature of mineral fiber.
Door :The door will be made of non corrosive acrylic with hinges in the rear. The door will be designed having inclined ceiling provided with side wall baffles to avoid droplets falling on to specimen as per ASTM Standard, Option of pneumatic Door lifting arrangement of user comfort for sample loading and unloading.
Air Compressor :
Motor : 1.0 HP, single / three phase
Control: Automatic pressure switch which maintains the pressure in Air Storage Tank.
Tank Pressure :100 PSI.
Pressure Gauge : 1 to 3 Bar
Safety : Mechanical pressure release valve.
Safety Features :
2 minute compressor “on” delay timer to safeguard the compressor. Compressors overload relay protector. Electronic low water level cut off device to cut off the supply to boiler heater in case of low water level. Safety Temp. Controller. MCB for mains.
