Mikrofill

The Mikrofill 3 Pressurisation Unit - EFD120021 is a Pressurisation Unit item. This product is manufactured by Mikrofill. Voltage for this item is 230V. It has an actual flow rate of 14 Ltr/min. This is a Surface Mounted pump which can be suitable when the pump can sit in a dry, accessible location and draw liquid in via a suction pipe or hose.

Unlike “pump type pressurisation units the Mikrofill 3 is developed to be connected directly to a buildings incoming mains/boosted water supply and fill a heating or chilled water system without the use of a pump.

The Mikrofill 3 utilises the energy already generated by the mains water or boosted water supply and does not contain an RPZ valve.

Pre – commissioned packages are available which include the Mikrofill 3 with appropriately sized vessels and service drain valves.

The operating pressure of this is 5 bar.

The Ethos Stainless Steel wall-mounted boiler range is designed and built in the UK for today's commercial buildings, combining reliability with simple installation.

With outstanding 10:1 premix burner modulation, an integral shunt pump and low-noise operation, the Ethos series sets a high bar. for efficiency and control in compact plantrooms.

• Stainless Steel heat exchanger for durability and performance
• 10:1 turndown for precise load matching and stable operation
• Onboard cascade control for multi-boiler sequencing
• Seasonal efficiency >96% to reduce running costs

The Ethos 70 delivers a 70 kW output with integrated cascade control; the range also includes 90, 110 and 130 KW models, with cascade options up to 780 kW.

The Mikrovent 1000 is a combined low loss header and air & dirt separator for connected loads up to 1000 kW, enhancing performance in commercial heating and chilled water systems.

As water passes the spiral-wound Stainless Steel brushes, a local low-pressure zone forms behind each filament, releasing dissolved gases. The lower brush encourages deaeration of dissolved gases, while the upper brush helps release entrained gases within the header. Separated air rises to the top and is discharged via the automatic air vent.

• Low loss header + air/dirt separation in a single unit
• Two removable Stainless Steel brushes for efficient degassing
• Automatic air vent provides continuous air removal
• Improves system efficiency by reducing air and particulate contamination

Mikrovent headers are available for connected loads of 150, 250, 400, 750 and 1000 kW, making them a smart addition to new or refurbished LPHW or CHW systems.
