Engineering scope tailored to your facility and process.

The areas below outline possible engagement scopes. Specific solutions, supply, works and documentation are defined after reviewing requirements and confirmed in the proposal.

01

Commercial refrigeration

Refrigeration systems tailored to product storage, display and distribution in retail and food-service facilities.

  • Cold and freezer rooms and zones.
  • Systems for back-of-house and display areas.
  • Solution selection based on facility use and operating conditions.
02

Process refrigeration

Solutions supporting production processes, product preparation and controlled storage.

  • Assessment of process requirements and temperature conditions.
  • System concept and equipment selection within the agreed scope.
  • Coordination with process equipment and plant operations.
03

Air conditioning and thermal comfort

Air conditioning for workspaces, customer areas, back-of-house and selected technical zones.

  • Review of room use and operating conditions.
  • Equipment selection and layout within the agreed scope.
  • Coordination of routes, power, drainage and controls.
04

Ventilation and indoor air

Supply and extract ventilation supporting appropriate air exchange in buildings.

  • Assessment of ventilation requirements and building layout.
  • Selection of air handling units, fans and system components as required by the project.
  • Coordination of system routes, service access and balancing.
05

Heating and heat pumps

Selection and delivery of heating and cooling solutions matched to building requirements.

  • Assessment of demand and system operating conditions.
  • Heat-pump selection and coordination with the distribution system.
  • Installation, controls and commissioning scope confirmed in the proposal.
06

Controls and system integration

Definition of equipment control and how building systems interact with building automation.

  • Definition of functions, operating modes and agreed monitoring points.
  • Coordination of signals, equipment and responsibilities.
  • BMS integration within the scope agreed for each facility.
07

Upgrades and commissioning

Work on existing systems and preparation for agreed acceptance and operation.

  • Assessment of upgrade scope and site constraints.
  • Delivery or coordination of agreed installation work.
  • Commissioning and documentation as specified in the proposal.

Typical applications

For facilities where reliable operation matters.

Every facility has its own process, schedule and constraints. We define the work after reviewing those conditions.

  • Retail, stores and food-service back-of-house.
  • Food service, hotels and customer-facing facilities.
  • Manufacturing and processing requiring controlled conditions.
  • Warehousing, logistics and commercial facilities.

Related departments

Controls supervision and integration are covered in BMS. Scent diffusion systems, including ventilation-integrated solutions, belong to Aroma.

How to get started

Prepare the location, facility type, required operating conditions and expected timeline. If existing system documentation is available, describe it in your inquiry.

  1. Send your brief through the form without creating an account.
  2. We clarify requirements, available data and responsibilities.
  3. We agree on deliverables, a schedule and proposal terms.

Design, installation, controls and maintenance responsibilities are agreed for each project. A service request does not confirm an attendance time.
