Frequently Asked Questions
Q: What cooling water quality is required?
A: We recommend clean fresh water or treated cooling tower water. Avoid hard water with high mineral content to prevent scaling. A water treatment system is recommended for continuous operation.
Q: Can this unit operate without a cooling tower?
A: Yes, it can use city water (once-through) for smaller installations, but a cooling tower or closed-loop system is recommended for continuous operation to reduce water consumption.
Q: What is the advantage over air-cooled units?
A: Water-cooled units maintain stable condensing pressure regardless of ambient air temperature, making them ideal for tropical climates and confined spaces. They also operate quieter since there are no condenser fans.
Q: Is anti-freeze protection included?
A: The water circuit should be protected against freezing if operated in cold climates. We can supply optional water-regulating valves and freeze protection accessories.
Q: How often does the condenser require cleaning?
A: Annual inspection and cleaning of the water side is recommended. Mechanical or chemical cleaning frequency depends on water quality. Our technical team can advise on a maintenance schedule.
