Renowned for developing innovative products, Mikrofill has built its success

on quality, reliability and outstanding customer service.

Our rapidly expanding range of products include commercial condensing

boilers, hot water loading systems and pressurisation equipment.

Mikrofill’s hot water loading systems have been developed specifically to meet

the demands of modern commercial buildings. The Extreme is a domestic

hot water generator that combines the advantages of both an instantaneous

hot water heater and a storage system, creating perfect harmony between

a condensing boiler and a hot water cylinder.

extremeThe Extreme principle addresses and overcomes all of the disadvantages of the traditional coil type cylinder, whilst remaining simple and straightforward to install. In addition the operating principle ensures the efficiency of a condensing boiler is optimised during the production of domestic hot water.

Mikrofill’s uncompromising approach to quality materials, design flexibility and engineeringexcellence has resulted in the Mikrofill Extreme, the new standard in hot water generation.

Exceptional flow rates in excess of 2500 litres an hour at 60ºC

Introducing ‘INJECTION DYNAMICS’, a breakthrough in domestic hot water technology. By utilising this revolutionary method of heating, the Extreme generates hot water faster, cleaner and more efficiently than ever before.

F E AT U R E S●Stainless Steel construction.

●Fully insulated, in excess of all current standards.

● Suitable for unvented and open vented systems.

●Available in 200, 300 and 500 litre versions.

●Maximum primary input of 120kw.

B E N E F I T S●Exceptional flow rates – up to 2570

litres an hour at 60°C.

●Injection dynamics – allowing hot water draw off in minutes.

●Optimises boiler cylinder efficiency – up to 94% with a condensing boiler.

●Positive stratification – greatly reduces the risk of Legionella proliferation.

●Design principle achieves 100% of cylinder capacity at 60°C enabling reduced storage requirement.

The Extreme is suitable for installation on both open and unvented domestic hot water systems and comes complete with a preinstalled pressure and temperature relief valve.

The unvented kit supplied includes the following items and is designed to work in conjunction with each Extreme cylinder.

●35 litre potable expansion vessel

●Pressure reducing valve (3.5 bar limit)

●Safety relief valve and tundish

●Check valve

●28mm 2 port valve (to provide a permanent means of isolation to the primary supply)

In addition each cylinder can be ordered with a factory fitted 3kW immersion heater.
