All our vans are fitted with oven cleaning dip tank as part of the oven cleaning system that we use. These are special tanks that use electricity to heat up the solution in them. They are securely bolted to the chassis of the van so they don't present a danger to the oven cleaning operative.
This compares to most other oven cleaning companies' systems where they use stainless steel trays that are heated up using a Calor gas burner. The tank isn't secured to the van, as it needs to be taken out of the van to heat up.The calor gas container and pipe work has to be kept in a serviceable condition; I have heard of an oven cleaning van catching on fire because of a faulty value.
Our system is the best there is and it is safe, fast and effective.Google+
