1. Продукт бүтүп калдыview
The ET MF-400 is a high-efficiency special heat exchanger designed for use in natatoriums, swimming pools, and spas. Its primary function is to transfer heat from a primary heat source (such as a heat pump or boiler) to the pool water, maintaining the desired water temperature.
This heat exchanger is constructed entirely from 304 дат баспас болоттон жасалган, both for its outer shell and inner components, ensuring durability and resistance to corrosion in typical pool environments. It is engineered for optimal heat transfer performance.
Important Note: This heat exchanger is not suitable for use with corrosive liquids, including seawater or saltwater. Use with such liquids will void the warranty and may cause damage to the unit and surrounding systems.

2. Components and Structure
The MF-400 heat exchanger features a robust design for efficient heat transfer. Key structural components include:
- 304 Stainless Steel Shell: The main cylindrical body of the heat exchanger, providing structural integrity and corrosion resistance. (Diameter Ø133x1.5mm)
- Internal Heat Exchange Tubes: Numerous smaller tubes made of 304 stainless steel (Diameter Ø10x0.6mm) run through the shell, facilitating the transfer of heat between the two fluid circuits.
- Black Insulation Paintcoat: Applied to the exterior to minimize heat loss and improve efficiency.
- Stainless Steel Holders: Brackets for secure mounting of the unit.

3.2 Орнотуу кадамдары (Жалпы көрсөтмөлөр)
- Жайгашкан жери: Choose a suitable location that allows for easy access for maintenance and is protected from direct weather exposure. Ensure adequate space for plumbing connections.
- Монтаждоо: Securely mount the heat exchanger using its stainless steel holders to a stable surface.
- Сантехникалык байланыштар:
- Connect the pool water inlet/outlet to the appropriate ports on the heat exchanger. This loop typically comes from the pool filter.
- Connect the hot water (primary circuit) inlet/outlet from your heat source (e.g., boiler, heat pump) to the other set of ports on the heat exchanger.
- Агып кетүүнү текшерүү: After all connections are made, pressurize the system and carefully check for any leaks before full operation.
- Изоляция: Ensure proper insulation of all hot water pipes to maximize efficiency.
It is highly recommended that installation be performed by a qualified professional to ensure compliance with local codes and optimal system performance.
4. Иштөө нускамалары
The ET MF-400 heat exchanger operates passively once integrated into your pool's heating system. Its function is to facilitate the transfer of heat from the primary heating circuit to the pool water circuit.
4.1 Алгачкы ишке киргизүү
- Ensure both the pool circulation pump and the primary heat source (e.g., heat pump, boiler) are operational and circulating water through their respective loops.
- Verify that there are no air pockets in the heat exchanger by bleeding air from the system if necessary.
- Monitor the pool water temperature and adjust the settings on your primary heat source to achieve the desired pool temperature.
4.2 Нормалдуу иштөө
Once installed and running, the heat exchanger requires no direct user interaction for its heat transfer function. Its efficiency is dependent on the flow rates and temperatures of both the primary and secondary circuits, as well as the cleanliness of the internal surfaces.
5. Техникалык тейлөө
Regular maintenance ensures the longevity and optimal performance of your heat exchanger.
- Үзгүлтүксүз текшерүү: Periodically inspect the exterior of the heat exchanger for any signs of corrosion, leaks, or physical damage.
- Суунун сапаты: Maintain proper water chemistry in your pool to prevent scaling or corrosion within the heat exchanger. High levels of calcium hardness can lead to scale buildup, reducing efficiency.
- Тазалоо: If a significant drop in heat transfer efficiency is observed, the internal tubes may require cleaning to remove scale or debris. This typically involves chemical descaling, which should be performed by a qualified technician.
- Кыштоо: In colder climates, ensure the heat exchanger is completely drained during winterization to prevent freezing and potential damage.
