Filter 10" - for hot water - 2 "F; without cartridge GEL.DEPURA 3000 OTR

Product detailed description

This 10-inch filter is commonly used in industrial and commercial hot water supply systems to remove mechanical impurities such as sand, scale, and rust particles. It is typically installed in central hot water lines, after the boiler or thermal storage unit, to protect downstream components such as heat exchangers, valves and circulation pumps. The filter operates in closed-loop systems where water temperature can reach up to 80°C. Installers should ensure proper alignment with the flow direction indicated on the body and verify compatibility with the selected filter cartridges.

Correct installation ensures effective filtration and long-term reliability. The filter is suitable for use in buildings such as hotels, hospitals, swimming pools and large residential complexes where high-quality hot water distribution is essential. The system must be designed to accommodate the nominal pressure rating of PN 8 and the thermal expansion characteristics of the piping network.

Technical parameters

Installation and connection

The filter is installed using 2-inch female threaded connections. A mounting key with code 125.210.50 is required for securing the head during assembly. Before installation, the system must be drained and flushed to prevent residual debris from entering the filter chamber. The filter must be positioned in the correct orientation to allow unobstructed flow through the filter vessel. Common errors include incorrect sealing between the head and the body, which can lead to leaks or reduced filtration efficiency. After installation, the system should be repressurised gradually while monitoring for signs of leakage.

Compatibility and accessories

This filter is compatible with DEPURA filter cartridges available in 10-inch and 10-inch/3000 configurations. For the GEL.DEPURA 1000 OTR model, a range of filter cartridges is supported, whereas the GEL.DEPURA 3000 OTR model is restricted to 10-inch/3000 cartridges only. To complete the installation, a suitable mounting key must be procured separately. Additional components such as isolation valves and pressure gauges may be necessary depending on the system layout and local regulations.

Technical background for designers

The filter operates by directing water through a porous medium housed within the TROGAMID vessel. The brass head resists corrosion and maintains dimensional stability under thermal stress. The TROGAMID body provides chemical resistance and low thermal conductivity, reducing the risk of condensation on the external surface. The system integration must consider the filter’s footprint and clearance requirements for maintenance access. Long-term performance depends on regular cleaning of the filter chamber and timely replacement of worn or clogged cartridges. System designers should account for the pressure drop across the filter when sizing pumps and selecting control devices.

Service and operation

Periodic inspection is recommended to ensure continued filtration efficiency. The filter body should be visually inspected for signs of wear or deformation, and the sealing surfaces checked for damage. The filter chamber should be emptied and cleaned according to the manufacturer’s instructions. No specific service intervals are provided in the technical documentation, so maintenance frequency depends on the quality of the incoming water and observed performance.

Frequently asked questions

Can this filter be used with water temperatures above 80°C?
No, the maximum operating temperature is specified as +80 °C. Exceeding this limit could cause material degradation and loss of sealing integrity.

What types of filter cartridges are compatible with this model?
For water temperatures above +40 °C, only stainless steel filter cartridges are approved. Refer to the DEPURA filter cartridge range for compatibility details.

Is a mounting key included with the filter?
No, the mounting key must be purchased separately under code 125.210.50.

Can this filter be installed vertically or horizontally?
The filter can be installed in either orientation, provided the flow direction matches the arrow marked on the body. Ensure sufficient clearance for maintenance and cartridge replacement.
