Block of liquid cooling WRA-300S, Cooler move 8,5l

The independent block of water cooling of the WRA-300S type, is intended for ensuring high-quality cooling and circulation of working liquid in the closed system, during the work with welding installations.

The block of cooling is used during the welding works on big currents (> 300 A) and are an integral part of the welding equipment (devices of argonodugovy welding, automatic welding semiautomatic devices, installations vozdushno of plasma cutting, etc.). In a welding torch the cavity of the handle and a head of a torch or a plasmatron, and also, depending on a design, the power cable can be cooled. If the block of autonomous cooling is operated with water, then ambient temperature has to be in the range from + 2C to + 40C.

Water use is extremely not desirable as the salts which are contained in it, being besieged on walls, form a salt layer. The salt layer as heat insulator, worsens cooling and increasing over time reduces liquid pass section that can put a torch or a plasmatron out of action. There is a special liquid for cooling of the welding equipment VST-15, production of the German company "BINZEL", with high heat-removing rates and the greasing properties for pumps of blocks. VST-15 blocks formation of an electrolytic raid (on the walls of the block of cooling which are giving and the taking-away tubes and internal cavities of torches) and can be applied from-15 winter to the +40th in the summer.

Structurally the WRA-300S block consists of the case in which are located:

1. Capacity for cooling liquid.
2. The electric pump with the fan.
3. Radiator for liquid cooling

The WRA-300S block is intended for work in the enclosed space and under a canopy with observance of the following conditions:

1. When using water ambient temperature has to be in the range from + 2 ºС to + 40 ºС; relative humidity no more than 80% at +20 ºС;
2. When using a coolant of VST-15 of Binzel firm temperature of the environment surrounding a cooler can be in the range from - 15 ºС to + 40 ºС.

1. Tank mouth for filling of cooling liquid
2. The handle for carrying
3. The switch a network with indication of the included state
4. Cut for visual control of level of cooling liquid in a tank
5. The quick-detachable union for a supply of cooling liquid to a torch (red)
6. The quick-detachable union for removal of cooling liquid from a torch (blue)

Set of delivery of the WRA-300S block:

1. The block of liquid cooling autonomous WRA-300S - 1 piece.
2. The nipple quick-detachable - 2 pieces.
3. Collar metal - 2 pieces.
4. The maintenance instruction (passport) - 1 piece.
5. Packing - 1 piece.
