Description

Pallas magnetic bag filter housings are devices for clarifying water in closed heating and cooling circuits. They are constructed of stainless steel and feature a high strength magnetic core with bag filter.

Closed water systems may contain suspended particulates of iron and other system materials. Deposition of these particulates can cause:

  • heat transfer loss – increase in energy usage
  • under-deposit corrosion – asset failures, downtime.
  • absorption of chemical treatment, making it difficult to maintain desired residuals.
  • pump seal leaks – water loss/makeup allowing oxygen ingress and system corrosion cycle.
  • bacterial habitat

Pallas magnetic filters are an effective response to these problems.

General
How does it work?

Set up

Magnetic Bag Filter Housing is set up in derivation on the return of the circuit to be treated. Mounting a balancing valve or a charge pump will force the flow  of the fluid in the filter.
The inlet and outlet isolation valves will also allow to use the filter as a pot for introducing products for the punctual treatments of the circuit.
Draining a low point to facilitate loading of the filter bag and cleaning of the magnetic bars.

Ideal installation

  • The filtration station is placed and fixed on the ground by its 3 feet
  • The filtration station is placed close to the preparation unit (9)(boiler,..),on the loop return circuit and at a suitable height in order to enable its connection to the unit of preparation and, on the other hand, its emptying by the drain present on its lower wall (shut off valve(5) and drainage of this drainage water.)
  • A shut-off valve will be mounted upstream(2) and downstream (6) of the filtration station to allow for maintenance without interrupting the operation of the plant.
  • A water inlet will be provided for filling with a shut-off valve(4).
  • An event ball valve (7) and a 10 bar pressure gauge(8) will be mounted on the cover with a 2 way connection.
  • A balancing valve (1) and a circulator(3)will be mounted in the loop return circuit.
Maintenance

Once a year*, clean the collector by changing the filter bag or cleaning it by turning it up and cleaning the magnetic bars with a dry rag.

Dismantling

1. Close the inlet and outlet valve.
2. Depressurize by opening the drain valve at the bottom.
3. Open event on top.
4. Loosen the wing bolts to pivot the lid.
5. Take out the spring and the magnetic system and clean with a rag.
6. Remove the filter bag from the stainless steel basket, clean it and/or replace it with a new one.

Reassembly

7.Repositionning the filter bag in the stainless steel basket as well as the bars.
8.Close the filter cover.
9.Close the drain valve.
10.Open the inlet valve until overflow by the event.
11.Close the event.
12.Open the outlet valve.

 

*For the technical reasons, the sludge collecting filters must be drained regularly according to the state and quantity of water in the circuit, at least once a year. At the time of this maintenance, clean the magnetic bars as well as the stainless steel sieve basket and change the filter bag.
Footnotes

Depending on the height position of the adjustable belt, the dimension "C" is variable.

General Technical Data

Technical characteristics

Every kind of particles with a size greater than 50 microns will be stopped by the filter bag while the high magnetic field magnetic bars  will capture all the ferrous particles resulting from the corrosion of the circuit.
In addition, the bag filter housing will allow the introduction of conditioning products such as corrosion inhibitors or antiscalant.
