Cooling Water Isolation System

Product Description

Purpose: To isolate the recirculating cooling water loop from primary cooling water. Can also be used for temperature control when used with a heat exchanger.

Problem:
Power Plants: Your Sampling System cooling coils are failing due to tube rupture. Or, the coolers become less efficient due to a severe build-up of scale on the coils, requiring frequent cleaning. Temperature control becomes difficult with heavily fouled coils.
Heavy Industry: You have scale build-up and fouling of your equipment's heat exchangers, requiring frequent cleanings and giving poor cooling. This can result in severe damage to sensitive equipment.

Solution: Install a JWT Cooling Water Isolation System.
Where used: Power plants, heavy industry, and other special areas.

Description: Cooling water may be of poor quality. River or lake water can contain high levels of salts, silt and biological organisms that foul heat exchangers. This reduces the efficiency of the heat exchanger and may result in tube failure on high temperature applications. Sea water or brackish water also has high levels of chloride, which can result in stress-corrosion cracking of high temperature tubes. A Cooling Water Isolation System eliminates these problems by providing isolation between the raw cooling water and the recirculating cooling water, and can provide automatic temperature control.

Options:
1. Dual Pump with auto-failover to backup.
2. Filter/strainer for incoming cooling water. This helps reduce fouling of the heat exchanger.
3. Heat exchanger backflush system. Reverse the cooling water through the exchanger to flush out entrapped solids.
4. Flow indicator for cooling water.
5. Control valve for raw cooling water, reduces water use when heat load is low.

Each system is custom designed for your application and includes the features you want, and only the features you want. In this way, you get the best system possible based on your budget and preferences. Please contact us to discuss your application.
