How we work in Derry
Measure
We measure the opening and check wind exposure and existing heating.
Select
The right width, air velocity and heat source are chosen.
Install
The unit is mounted and connected to power, water or refrigerant. We keep work areas in Derry screened and tidy at the end of each day.
Set up
Door contacts and controls are set so it runs only when needed.
Things to check in Derry
Exposure
Windy entrances need more powerful units or a lobby.
Conservation areas
Historic streets and listed buildings in and around Derry are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.
Heat source
Heat pump air curtains are usually cheaper to run than electric ones.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Types of premises we cover in Derry
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
In Northern Ireland, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under EU F-gas rules that apply in Northern Ireland, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
