WATER BATH FOR PLYWOOD SECTION-GMP-
Model Number : EIE-408.HCS-
Testing of plywood and other wood-based products for water resistance and wet bending strength as per IS 303: 1989, IS 1659: 2004, IS 710: 2010 and IS 4990: 1993
Application:
Testing of plywood and other wood-based products for water resistance and wet bending strength as per IS 303: 1989, IS 1659: 2004, IS 710: 2010 and IS 4990: 1993
HEATING + COOLING FACILITY:
Temperature is Controlled from 10°C to 100°C ± 2°C curing temperature.
Can be controlled at 27 °C ± 2 °C for Normal curing or up to 100 ± 2°C For Accelerated curing by boiling water method
Also, it will have capacity for curing by warm water method at temperature 55 ± 2°C.
The whole body of cube mould with the sample of concrete/cement mortar inside is to be immersed in the tank and the Tank is stout enough to bear heavy load on its platform.
Provided with water inlet and outlet valves.
Construction:
- Double walled stainless steel construction with inlet/outlet to fill/drain water, stirrer and pyramid type lid
- Outer surface shall be epoxy painted.
Safety:
There will be proper insulation / water proofing arrangement separating controller circuit area from water bath chamber to prevent steam/moisture entering controller/instrumentation box area.
Water filling arrangement:
- Will have metallic (rust free material) float valve arrangement to ensure auto fill for continues operation with ½” supply line.
- Float valve Will be of good quality metallic material for longer life.
Operating conditions:
The equipment will be capable of running 96 Hrs continuously at 100°C without any error during weekdays and 100% leak proof and capable of maintain temperature from ambient to 100°C or 27±2°C and of achieving uniform temperature.
Spares and AMC service:
- Spares will be readily available for ensuring timely maintenance.
- List of spare parts (with specifications) will be provided at time of delivery.
