We are proud to announce that we have been ranked first in the category of top exporters of chiller units also in 2024 after 2023.
Yes, the use of antifreeze is essential in chiller systems to prevent the risk of freezing and to ensure long-term, efficient operation. The recommended concentration typically ranges between 25% and 50%, depending on the ambient temperature. Manufacturer recommendations should always be taken into account.
In such systems, the water temperature must never fall below 5°C. If the system is not going to be in operation, the water inside should be completely drained. Additionally, proper insulation of the system and control of the ambient temperature should be implemented as extra precautions.
Chiller systems require a specific water flow rate to operate efficiently. If the pump delivers a higher flow rate than the system requires, the excess water is redirected to the return line through a bypass line to prevent any potential damage to the system. This setup also helps stabilize pressure fluctuations within the system.
The by-pass line should be directly connected from the pump discharge line to the chiller return line. A control valve must be installed on the line and adjusted according to the system’s flow rate requirements. It is important that the line is installed with the correct diameter and over the shortest possible distance.
The refrigeration cycle is a closed system, and unless there is a leak, refrigerant replacement is not necessary, as it does not lose its properties over time.
Filters, oil, antifreeze levels, and electrical connections should be checked periodically and replaced if necessary. The maintenance interval is typically scheduled every six months.
All electrical connections, control panel, compressor, gas pressures, water filter, antifreeze level, and insulation should be examined in detail.
A minimum clearance of 2 meters should be left around the unit for service access. Condenser airflow must not be obstructed, and the unit should be kept away from direct sunlight and structures that block air circulation.
The canopy should be installed at a height taking into account the unit’s capacity/size to prevent the recirculation of hot air in the direction of the fan discharge, with a minimum clearance of 3 to 6 meters. If necessary, hot air should be directed outside using ducting or canopy system. Due to the external static pressure that the condenser fans can handle, installation should not proceed without the approval and consultation of the supplier.
Using a water line diameter/piping that deviates from the required specifications and design calculations significantly impacts fluid flow velocity and can lead to various risks. Undersized piping increases fluid velocity, causing reduced flow rates, turbulence, and high-pressure drops, which can result in excessive wear and premature failure of equipment. Conversely, oversized piping decreases fluid velocity, leading to inefficient system operation, sediment buildup, and increased risk of corrosion. In both cases, system performance is negatively affected, energy efficiency declines, and equipment lifespan is shortened. Therefore, it is critical to select pipe diameters that comply with proper flow velocity and design criteria.
Strainer: Integrated into the piping system. Commonly used in Y-type or basket-type configuration. Captures large particles such as debris, welding slag, and other contaminants. Protects key components such as the evaporator, pump, and valves from damage.
Line Filter: Provides finer filtration. Used in special applications requiring the removal of micro-particles. Dirt Separator: Continuously removes suspended particles using magnetic or cyclone-type separation
The cable cross-section should be appropriate; neutral and grounding must be properly connected, and leakage current and circuit breaker protection systems should be active.
A flat, sturdy, and vibration-damping base should be prepared; vibration pads must be placed between the unit and the foundation.
A chiller unit should be maintained twice a year, prior to the summer and winter seasons. Additionally, for intensive usage, time-based maintenance can be scheduled (for example, every 5,000 operating hours). During maintenance, it is important to clean or replace filters, check oil levels, evaluate antifreeze levels and quality, inspect electrical connections, and check for possible leaks in the system. Periodic maintenance ensures efficient operation of the chiller, prevents breakdowns, and extends the equipment’s lifespan.
Maintenance costs depend on the equipment capacity, site location, and labor duration. Firms with a service agreement receive preferential terms.
Remote support is provided 24/7. Physical service requests are responded to within a maximum of 48 hours.
Spare parts are available for standard products for up to 10 years, excluding technological changes.
No. The use of inhibitor-treated antifreeze is recommended to prevent freezing and corrosion. A water/antifreeze mixture is the ideal solution.
No. It operates according to the system’s demand. When not in operation, antifreeze levels should be monitored, or the system should be drained.
Yes. Inhibitor-treated antifreeze should be used to prevent freezing, and system insulation must be checked.
No additional fluids are required in the refrigeration cycle. However, on the water side, antifreeze levels should be regularly checked and replenished as needed.
User errors, external impacts, improper installation, and power supply issues are excluded from the warranty. All other manufacturing-related defects are covered under warranty.
