### Instruction:

Create a detailed description for the following product: Oxen, belonging to category: Heat Recovery Ventilation System

### Response:
The Oxen is an economical heat recovery ventilation system which is easy to operate. It reuses energy recovered from ventilation so that up to 94 per cent of this energy can be regained. The system was designed especially for large spaces, such as production halls, exhibition rooms and public facilities. Compared to already existing solutions, it is compact and creates a decentralised, independent ventilation system which can be installed without additional ducts.
