The therm 715 is an excellent robust design, and a powerful hot and cold pressure washer running on an ordinary UK 3-pin plug (240 volt) Durable for industrial and commercial use.
The pressure of the therm 715 can be fully adjusted and at maximum will give nearly 2000 psi. This is actual pressure at the nozzle, unlike low pressure chemical injectors, here the actual pressure is around 30% higher than traditional systems – something true of any pressure washer with low pressure chemical option.
The boiler unit or combustion chamber is probably the best used on any make of mobile steam cleaner. Most on the market are formed out of a thin tin like material. Kranzle therm casings are machined out of 1/4″ inch galvanized plate steel.
The flame chamber is within an inner cylinder ensuring that the flame does not directly touch the coil. This refinement eliminates sooting up – a common problem with other steam cleaners that leads to smokey exhaust, poor efficiency and higher servicing costs. Kranzle are renowned for low servcing costs and excellent efficiency.
The Kranzle therm 7-series are equipped with a digital flame monitoring device. A photocell is located right above the combustion chamber and connected to the central control electronics. If the photocell does not detect a flame, the fuel supply is cut off. This prevents a dangerous build up of unburnt fuel inside the burner.
The Kranzle coil has a huge surface area of over 22 square feet and because both the fuel and air are pre-heated, combustion of the fuel and the water heating process is extremely efficient. Therm’s have been designed with simple maintenance taken into account. Every Therm machine is fitted with both an easy to clean fuel filter and a fuel pressure gauge. Low fuel cut out is standard, as is pre-purge venting.
The output temperature is adjustable with a steam stage of up to 140°C. Detergents can be used at high pressure giving the maximum cleaning combination of high temperature, high pressure and chemical.When you let go of the trigger gun, the therm 7-series switch off to stand-by mode if the trigger gun is not operated for 30 seconds, this delayed shutdown reduces unnecessary ‘on/off’ operation when say freeing the hose. When the trigger is squeezed again the machine instantly restarts. As an added safety feature, if you forget to switch the machine off after use it will switch itself off after 20 minutes of standing idle. The therm 7-series are supplied with stainless-steel lances with quick-release fittings and our heavier duty Starlet II short quick-release trigger gun.
There are convenient to get to storage compartments for the trigger gun and lance built into the casing of the machine and a tray which can hold a 5 litre bottle of cleaning agent.
Models without the hose drum come with 10 M of high pressure hose.
Optional T-Series comes with hose drum, and then includes a 20 M high pressure hose.
A major advantage to the new generation of pressure washer from Kranzle is that you can clean with detergents and degreasers at high pressure.
This is a big help when cleaning engine compartments, gearboxes or pre-MOT cleaning on HGVs. It also increases the effectiveness of cleaning where hygiene and BIO-SECURITY is essential such as on farms, in areas with livestock, kennels or any food handling areas.
The water tank on a Therm also protects the pump from being starved of water. On a conventional pressure washer attached to a tap via a hose if there is not enough water flow to the pump the pistons inside are held forward by the vacuum that forms on the inlet. This causes knocking in the transmission and serious damage to the pump if not rectified. The water tank on the therm 715 acts as a buffer between the water mains and the pump and compensates for fluctuations in the supply – protecting the pump.
Therms are easy to use, versatile, well designed, easy to maintain and have long life expectancy. Every effort is made to make the machine that is the best on the market and yet still affordable. This is it, overall an excellent value for money machine and exceptionally durable.
