FUNKE Plate heat exchangers

For more than three decades FUNKE has specialised in the development and manufacture of heat exchangers with up to 2000 m² heat exchanger surface for all current industrial applications and designs.

In the field of Plate Heat Exchangers FUNKE offers a sophisticated range of products able to meet almost any requirement in machine and plant engineering. FUNKE's special “off-set” system with asymmetrical flow gaps creates highly efficient and cost-effective apparatuses whose performance (depending on design) is up to 17 percent higher compared with conventional plate heat exchangers.

Bolted Design (plate & frame)

FUNKE - heat transfer plates are characterised by optimum embossing resulting in high heat transfer coefficients. This permits low-cost and optimum adaption to the respective application conditions Our product range includes single-pass and multi-pass plate heat exchangers with heat exchange surface up to 2000 m².

Brazed Plate Heat Exchangers

The series GPL, GPLK und TPL provide for a well balanced ratio of high heat transfer rates with low pressure losses. The thermodynamically optimized corrugation of the embossed plates and the inserted turbulators (TPL) allow for high turbulent flow even at low volumetric flow rates. This allows for efficient use of the heat exchange area available and leads to a perfectly optimized heat transfer. The high turbulent flow also results in an efficient self-cleaning effect, which greatly reduces maintenance and time-out. FUNKE brazed plate heat exchangers have a compact design and are used for high pressures and temperatures.

Service

As based on the requirements of our customers, warranty and post–warranty services, including pressure tests, are offered by our team, which is certified for such operations. When applying various types of chemicals, including alkalis (ammonia), we have facilities to exhaust the chemicals/acids from heat exchangers. Cleaning of the plates is performed mechanically, in combination with pressurized water, or in a bath for chemical cleaning of the plates, if such procedure is necessary. The service can be provided either on site at the customer’s location, or the plates can be transported to our service center for further processing (chemical cleaning).

Leak Detection

CHEMICAL CLEANING OF PANELS

We perform chemical cleaning of panels on an alcalic or accidic basis, depending on the type and degree of fouling, including subsequent passivation in a passivation solution.

After the chemical cleaning the panels can be electrolytically polished.

UV DEFECTOSCOPY OF MICROCRACKS IN INDIVIDUAL PANELS

We are happy to offer you modern ultraviolet defectoscopy of individual heat exchanger plates (applicable to tanks, pipes, fittings, etc.).

This quick and relatively clean method not only reveals but also locates any microcracks – including surface defects of the material.

We provide this service at the customer’s site, or we take the panels to our service centre where we carry out the tests in the “comfort” of our technical facilities.

CHEMICAL FLOW CLEANING OF EXCHANGERS

Our mobile unit is a special flushing device designed to clean cooling and heating systems. It heats up the cleaning fluid and increases cleaning efficiency. The unit can flush the system with variable intensity and direction while filtering the flushed dirt with a coarse filter in the filling hole and a fine filter before the pump, which prevents the dirt from returning into the system. The unit is powered by 400/230V. In the case of 230V power supply the heating power is reduced to 1/3, making it necessary to take into account a longer cleaning period. The flushing device is designed for cleaning and flushing heat exchangers, water distribution systems, pressing and injection moulds, coolers, pumps, boilers, and all types of cooling and heating circuits where the system is clogged by deposits formed by the medium used.

WHY CLEAN COOLING AND HEATING SYSTEMS?

Limescale is an excellent insulator – a layer of 0.1 mm reduces the efficiency of the heat exchanger by up to 30%. This layer of limescale grows in average hard water within 6 months, and after 12 months the layer can reach up to 0.5 mm. After 18 months it may no longer be effective.
