HVAC: Protection of Heat Exchanger & Pump  

Reference in Heating Ventilation Air-Conditioning systems 

The Hepworth Gallery trusts BOLLFILTER for the protection of heat exchangers & pumps of HVAC with automatic filters.

Paintings and other delicate artworks require critical atmospheric management. The River Calder location provides an ideal renewable energy solution for this building, rather than the usual gas or oil-fuelled boiler typically found in the basements of such buildings. A “Liquid to Air” water cooling and heating distribution HVAC system with under floor heating was designed for this location. The system works via an array of pipes, heat exchangers, pumps and control units.

Filtration of the river water 

For this  application, a dual bank of duty pumps each with a BOLLFILTER automatic were fitted to filter the river water down to 500 micron to protect the heat exchangers. The BOLLFILTERS prevent blockage of the heat exchangers to ensure the required flow is maintained, resulting in efficient heat transfer and therefore efficient cooling and heating of the building. BOLLFILTERs are a fully automated, robust units which backflush the accumulated debris to waste, controlled by timers with DP override. 

Water quality improvment 

The water quality has improved substantially due to the performance of the BOLLFILTER Automatic, which has reduced the contamination in the system to a minimum and ensures smooth operation. It has gained in thermal output and therefore improved the operability and regeneration of the system. Installing BOLLFILTERS for solid removal will extend the lifetime of a typical HVAC system. The BOLLFILTERS require minimal maintenance and will operate for many years.


Reference in seawater cooling system for HVAC

NOCS, one of the world’s top five oceanographic research institutions, has taken advantage of its dockside location to help reduce energy consumption by means of a unique seawater cooling system (SWC). The cooling system utilises seawater during the winter months to indirectly cool the building via a heat exchanger.

A BOLLFILTER Automatic, self cleaning filter has been fitted prior to the heat exchanger. This operates continually to remove marine detritus, such as seaweed, from the water and helps maintain the efficiency of the system.

The system reduces electricity demand by approximately 5% per year, saving an estimated 117 tonnes in carbon dioxide emissions a year.
