Ventilation & Air Conditioning Solutions

DETAIL SERVICES

Air conditioning, ventilation and environment control for factories, offices, hotels and production areas.

Comfort cooling and industrial ventilation are two different problems. An office needs zoning and quiet running. A production hall needs heat extraction, fresh air changes and ducting that does not fight the process equipment. A curing room needs humidity held within a few percent.

DOV handles system design, electrical connections, controls and automation, ducting, testing and commissioning on all three.

Our Ventilation & Air Conditioning Services

Air Conditioning Systems

We provide air-conditioning systems for offices, hotels, commercial buildings, industrial facilities, food-processing environments and other specialised applications.

Each system is planned according to the required cooling capacity, indoor conditions, building layout, operating hours and future expansion requirements.

Our Solutions Include

Air Handling Units (AHU)

AHUs for offices, hotels, factories and production halls. We select coil capacity, fan static and filtration against the actual air change and load requirement of the space, then install the unit with its ducting and controls.

  • Supply and installation of AHUs, any capacity
  • Cooling coils, filters, fans and dampers
  • Fresh air and return air configurations
  • Ducting, insulation and air distribution
  • Controls, automation, testing and commissioning

Zoned systems for buildings where each area runs on its own schedule. Rooms that are empty stop drawing power, which is where the running cost saving comes from over a central system.

  • VRF and VRV system design and installation
  • Indoor unit selection: cassette, ducted, wall and floor mounted
  • Refrigerant pipework, drainage and electrical
  • Centralised and individual controls
  • Testing, commissioning and servicing

Chiller-based air conditioning for large floor areas. Above a certain building size, chilled water beats DX on both running cost and serviceability, because the plant is in one place and the distribution is water rather than refrigerant.

  • Chiller plant selection and installation
  • Chilled water pipework, pumps and insulation
  • AHU and FCU distribution networks
  • BMS integration and controls
  • Commissioning, balancing and maintenance

FCU supply, installation and pipework for chilled water systems. Room-level control on a central plant.

  • FCU supply and installation, ducted and exposed
  • Chilled water pipework, valves and drainage
  • Thermostat and zone controls
  • Commissioning and water balancing
  • Servicing and coil cleaning

Ventilation Systems

Ventilation systems help introduce fresh air, remove heat, odours, fumes and contaminants, and maintain suitable indoor conditions.

We design ventilation solutions according to the building’s use, occupancy, process requirements, heat generation, air-change rates and safety considerations.

Our Solutions Include

Fresh Air Handling Systems

Fresh air units for production halls, clean areas and any space where air change rate matters as much as temperature. Filtered, conditioned outside air, delivered at the volume the process requires.

  • Fresh air handling units, supply and installation
  • Filtration to the grade your process needs
  • Pre-cooling and dehumidification of incoming air
  • Ducting, diffusers and distribution
  • Testing, commissioning and air balancing

Cabinet fan exhaust for kitchens, process areas and fume extraction. Enclosed fan units run quieter and are easier to service than open axial installations.

  • Cabinet type exhaust fan supply and installation
  • Commercial kitchen extraction, including hoods and filters
  • Process and fume exhaust
  • Ducting, dampers and discharge arrangements
  • Servicing and filter replacement

Heat and fume extraction for factory floors, machine rooms and plant areas. Removing process heat at source costs a fraction of trying to cool the whole building afterwards.

  • Industrial extraction and ventilation system design
  • Roof extractors, wall fans and ducted systems
  • Machine room and plant room ventilation
  • Heat, fume and dust extraction
  • Installation, commissioning and servicing

Duct fabrication and installation. Badly designed ducting wastes fan power and makes rooms noisy, and it is the part most often value-engineered out of a job.

  • Duct fabrication in GI and other specifications
  • Installation, support and insulation
  • Grilles, diffusers, dampers and registers
  • Air balancing and flow measurement
  • Modification and extension of existing ductwork

Environmental Control Systems

Certain industrial, commercial and processing environments require more than standard cooling.

DOV Engineering Services provides environmental-control solutions designed to maintain specific temperature, humidity and air-quality conditions.

These systems are suitable for facilities where environmental stability is important for product quality, process control, equipment protection or occupant safety.

Our Solutions Include

Industrial Humidifiers

Humidification for storage, curing, printing and packing areas where product dries out or generates static if moisture is too low.

  • Steam and evaporative humidification systems
  • Sizing against room volume and required RH
  • Curing, storage, printing and textile applications
  • Controls, sensors and integration with AHUs
  • Installation, commissioning and servicing

Rooms built and controlled to a specified condition, holding both temperature and humidity inside a narrow band. Ripening, curing, testing and controlled storage.

  • Design and construction of controlled environment rooms
  • Combined temperature and humidity control
  • Ripening, curing, testing and storage applications
  • Panel construction, refrigeration and control systems
  • Monitoring, logging and alarm systems

Dehumidification for cold stores, warehouses and processing areas where moisture causes condensation on product, frost on evaporators or ice on floors. A dehumidifier is usually cheaper than repeatedly defrosting a plant that is fighting a humidity problem.

  • Desiccant and refrigerant type dehumidifiers
  • Cold store, warehouse and processing area applications
  • Sizing against moisture load and target RH
  • Supply, installation and commissioning
  • Servicing and desiccant wheel maintenance

Filtration and air curtain solutions for hygiene sensitive production areas. Keeping contamination out of a processing hall is cheaper than dealing with a failed audit.

  • Air filtration systems and filter housings
  • Air curtains for doorways and openings
  • Positive pressure systems for clean areas
  • Filter supply, replacement and servicing
  • Hygienic ducting and air distribution
