Removing an oil tank is a mandatory operation when you want to change or upgrade your heating system. Our teams accompany you in this process: from advice to the evacuation of the oil tank.
Due to the nature of the products contained (fuel oil, deposits/sludge, gas), this operation must be carried out by trained and qualified professionals in order to control all risks for people, property and the environment.

Different sensitive operations are essential before proceeding with the removal of your tank:
– Emptying, degassing and cleaning
– Neutralization
– Dismantling and removal
– Waste management
– Certificate of conformity

Ortec’s local teams carry out all of these operations while controlling the risks and complying with regulations.
