A pressure drop dilemma – truth or fiction? Can anyone help solve the mystery?

The crime scene: There is a water system containing all of the usual fittings being pumped around a building by a pump in the basement. The pipework is DN150. The water flowrate is around 18 litre/sec making the pipe velocity around 1 m/sec. A gasketed plate and frame type heat exchanger (PHE), also in the […]

Getting the most from a Heat Pump Heat Exchanger

A common mistake made when specifying and selecting heat exchangers to be used as circuit breakers between a heat pump and a building is as follows. Example: 16 kw heat pump Heat pump providing a hot fluid at 55 deg flow and 35 deg C return. Needs to heat cold water in the heating loop […]

Plate Heat Exchangers used in free cooling applications – in some cases, do you end up with what you have paid for instead of what was asked for?

To take full advantage of potential energy savings that can be gained from free cooling, the heat exchanger must be selected correctly but it is not always easy to determine the best choice of supplier due to a surprising variation of sizes and prices available. Once closely examined it can transpire that the cheapest price […]

How to quickly calculate the steam consumption of a heat exchanger without the fuss and feel enlightened like this fella

There are a few methods that have been advertised and can be used, to determine steam consumption, but most of these involve the use of steam tables. However, few of us carry about a set of steam tables, especially when down in some darkened plant room with no internet connection, or another field location, so […]

10 things that you may have not known about Gasketed Plate and Frame type Heat Exchangers

Suspended or dissolved Solids Similar to what happens in a flowing river – changes in velocity and direction can caused the solids to drop out of the general flow. If these particles stick together then a blockage can occur at the top / bottom of channels between the plates, or actually inside the channels. To […]

Wort Cooling Heat Exchangers

Which along with heat transfer, reduce your carbon footprint, save energy and lower heating costs We can offer a range of Gasketed Plate and Frame type Heat Exchangers that have been selected to cool the wort when it is being transferred out from the brew kettle into the fermentation vessel so that yeast can be […]

Is it time to add antifreeze to protect your heat exchanger?

The temperature has been dropping, so is it time to add antifreeze to protect your heat exchanger? The benefits of protecting a heat exchanger from freezing are well known, but are there any downsides to using anti-freeze? If the heat exchanger was originally selected using calculations based on water only, then the answer is “yes”. […]

Batch Heating and Cooling

A warning to Companies and Installers wishing to heat or cool the contents of a tank over a period of time using an externally mounted heat exchanger. When a tank of liquid is either heated or cooled over a period of time, it is commonly referred to as a “batch process”. The tank contents are […]

Quick Guide to Determine Pressure Drops

Need a quick way to determine what happens if you increase or decrease a water (or any other Newtonian Fluid) flow through a Plate Heat Exchanger? Do not have time to phone up the supplier, talk to someone who is not really interested in helping you because there is no potential sale involved, only to […]
