Ehrle HD Range

The HD series is Ehrle's professional-grade hot-water pressure washer range. Each HD steam cleaner is designed for the most stubborn industrial messes, with each one boasting individual specifications of Ehrle's high-performance pump design (a design they use in several ranges), handy quick-coupling systems, and Etronic I (623) and II (823, 940, 1140, 1240) controls.

Who needs an Ehrle HD?

In our experience, industrial and commercial businesses that require a high-performance hot pressure washer on site but need it to be manoeuvrable across that site favour the HD series. In other words, unlike for things like vehicles, which are themselves mobile, an HD is needed for objects and spaces that need to be deep cleaned, possibly sterilised (very high-temperature cleaning), but which span large premises and, potentially, multiple locations. (That being said, they do superb work on vehicles too. Many hauliers use our HD range too, for instance.)

In addition to this mobility, the HD’s dosing valve makes intensive detergent application a breeze. Therefore, companies that are required to maintain the highest level of hygiene and need to apply detergents and chemicals frequently benefit from this mechanism.

For these reasons, the HD series is a hugely popular range amongst companies in the food and agricultural sectors. Often requiring the cleaning coverage of extensive premises or for a multitude of cleaning tasks, the HDs offer both the high-performance specifications and versatility that these businesses commonly require. 

Which HD should I get, and how can I get one?

Each HD  (623 - 1240) is a stalwart steam cleaner. All of them boast specifications (see below) that are enough to dominate the lion’s share of cleaning tasks. 

The main thing to bear in mind is the electrical power requirements for each machine. If an HD boasts the digit 23 in its model number, it means it is a single-phase pressure washer that can run from a mains 230V supply. If it boasts a 40 in its model number, it is a three-phase jet washer that requires a 400V supply. Obviously, therefore, you must have a suitable power supply for the desired steam cleaner.

The advantage of the 230V pressure washers, such as the HD 623 and HD 823, are there versatility. Running on a mains supply, standard three pin plug, its easier to find a power source for them.

The advantage of the 400V pressure washers, such as the HD 940, HD 1140 and HD 1240, is the additional power input. Power input equals power output. Therefore, running more powerful pump and motor combinations, the 400V pressure washers can also generate more pressure at higher flow rates.

If you have any questions or think an HD pressure washer could be for you, please do not hesitate to get in touch with us by phone (01652)659759 or via . We will be more than happy to discuss and assess your needs and offer advice on your requirements. We can also give you that all-important detail, a price quotation! 

What about the other models of HD that Ehrle do?

We list most of the available HDs on our website, and we may eventually list all of them. Being Ehrle’s No.1 UK dealer, we can supply the full range. However, based on our 25-years of experience, we have found certain specifications that suit our customers’ needs far beyond others. For instance, the HD1140 is a best seller, which is unsurprising given its hefty performance specifications and reliability. Therefore, we have decided to list those machines, in all series, that perform optimally for the cleaning work our customers tend to do. 

Modification

Beyond the base models, we can also modify some HD models. For example, we can alter parts in certain builds to add greater pressure and water flow outputs, improving their cleaning performance. This can be an economical means of getting a more powerful pressure washer. However, there can be things to bear in mind, such as power supply requirements and the work you are doing. Therefore, for specifics, we would recommend getting in touch via the messenger icon on our website, by email () or phone 01652 659759. 

Premium or Standard?

The performance specification remains the same between standard and premium options as the base HD remains exactly the same. Instead, the premium comes with a number of peripheral upgrades and extras. For example, a premium HD comes with a 20m hose reel rather than a 10m hose, and a turbo lance.

Hot or Cold?

Is hot water cleaning best for you? If you have a hot water and cold water machine of the same specifications, the hot water cleaner would likely make lighter work of a cleaning task than the cold water pressure washer. Heat simply helps loosen and break up dirt and grime. It’s particularly good at dispersing oily messes too. However, this comes at the cost of additional weight, size and power. 

The equivalent cold water range, to the HDs, is the Ehrle KD series. Not requiring a burner, or fuel tank to power that burner, the KDs are smaller. The KD 623, for instance, is about 100kg lighter than the HD 623. 

As the number relates to specifications, the KD 623, 823, 940 and 1140 boast the same pressure and water flow rates as their HD counterpart. Only, they are cold water machines. The KD range also extends into more powerful specifications too, with the KD 1340 and KD 1540 producing additional cold water cleaning power.
