Product catalog summary

Specifications
The Dolphin Optimum filters by Heation AB are designed for liquid filtration, featuring a maximum flow rate of 550 m³/h and nominal pressure ranging from PN 10 to PN 16. They can operate at temperatures up to 90°C and are constructed in Y, L, and O shapes to suit various installation needs. The filters are compliant with the PED 2014/68/EU design standard and are suitable for liquids with salinity less than 10000 ppm and pH between 3 and 9.

Materials and Construction
The housing is made from AISI 304 or AISI 316 stainless steel, with EPDM gaskets certified for drinking water contact. The filters feature a QUICK BOLTS system for easy maintenance and an anti-cutting stop to extend gasket life. Vent/drain valves and pressure gauges are also made from high-grade stainless steel.

Models and Flow Rates
The datasheet lists various models with different construction shapes and sizes, each with specific maximum flow rates and filtering surfaces. For example, the OPH DN250 S50 model has a maximum flow rate of 550 m³/h and a filtering surface of 7400 cm².

Cleaning and Maintenance
Manual cleaning is required when the pressure differential exceeds 0.8-1 bar. The filter can be isolated, emptied, and opened to remove the FILTERKIT for cleaning or replacement.

Filtering Elements
Three types of filter kits are available: PES, 2LE, and 1LE, each offering different filtration degrees and materials. The PES kit uses a polyester filter fabric, while the 2LE and 1LE kits are made entirely of AISI 316 stainless steel, suitable for more challenging conditions.

Accessories
Accessories include a Differential Pressure Kit for monitoring pressure differences and Neodymium Magnetic Rods for capturing ferrous particles. Eyebolts and spare parts like gaskets and pressure gauges are also available.

Contact Information
Heation AB is located at Laxholmstorget 3, 602 21 Norrköping, Sweden. They can be contacted via email at [email protected] or phone at +46 (0) 763102470.

dolphin - optimum datasheet Filtering elements PES filter kit This filter cartridge consists of a stainless steel AISI 316 mesh cylinder supporting a layer of polyester (PES) filter fabric. This design offers a wide range of filtration grades and easy maintenance. Filter fabric AISI 316 Support mesh AISI 316 Filter mesh This filter cartridge is made entirely of AISI 316 stainless steel, consisting of a filter mesh welded to an outer support. This filtering element provides greater resistance compared to polyester and is recommended for more challenging operating conditions, such as the presence...

dolphin - optimum datasheet Differential Pressure Kit Enables monitoring of the pressure difference between the filter's inlet and outlet. By doing so, it allows the connection of an alarm that activates when the AP reaches the preset value, alerting maintenance personnel that the filter requires cleaning. Max pressure AP range Max temperature Neodymium Magnetic Rod The kit includes neodymium magnetic rods coated in AISI 304 stainless steel. These rods attract and retain even the smallest suspended ferrous particles from the filtered liquid, making them easy to remove during regular filter maintenance....
