VRF/ VRV Air conditioning system- heat recovery

  • Smart climate control with Multi-floor VRF (Variable Refrigerant Flow) air conditioning system
  • Heat Pump providing refrigeration to indoor units, including pipework, cabling, condensate, and HVAC Systems installation)

Mechanical Heat recovery ventilation

  • Energy-efficient heat recovery ventilation system
  • Strip out the plant room equipment to allow PEG-installed services (ventilation solutions)

General ventilation

  • Extract ductwork, fire dampers, and grilles.

Fire smoke dampers

  • Advanced safety systems installed fire/smoke dampers with a smart control system

Air treatment, including carbon filters 

  • Enhanced air treatment system incorporating multi-stage filtration, including activated carbon filters, to eliminate odours, VOCs, and airborne contaminants.
  • Complete installation includes pre-filters, carbon filter housings, access panels for maintenance, and integration into HVAC ductwork, ensuring high indoor air quality and compliance with ventilation performance standards.

SmartVent controls

  • Intelligent ventilation control system enabling automated regulation of airflow, temperature, humidity, and air quality across multiple zones
  • Installation includes centralised SmartVent control panels, user interfaces, integrated sensors, BMS connectivity, and remote access capability to optimise energy efficiency and ensure responsive indoor climate management.

Mechanical MCC controls

  • Installation of 2kW electronic radiators, electrical control, MCC panel controls

Plumbing services and associated controls

  • Plumbing installation covering all boiler room requirements and full sanitary provisions  
  • Supply and installation of equipment for the boiler room: gas boiler, clarifier, pumps, booster set flues, pressurisation unit, controllers, pipework, and lagging
  • Commercial plumbing services: installation of soils and wastes
  • Supply and installation of cold-water supply (CWS), hot water supply (HWS), hot water return (HWSR), and mains water supply (MWS)
  • Grease trap plumbing
  • Flushing out and chlorination of storage tanks and lines

Gas services and associated controls

  • Comprehensive gas system installation with leak detection
  • Gas pipework installation
  • Gas panel, gas leak detection, and gas interlock system

UVC Kitchen extract system

  • High-efficiency UVC technology integrated into the kitchen extract system, sterilising and removing odours and grease to discharge cleaner, safer air
  • Reduces grease build-up inside ductwork, significantly lowering fire risk
  • UVC light actively destroys bacteria, viruses, and odours in the exhaust air
  • Integrated with stainless steel canopy extract hoods and ducting, reducing the need for frequent manual cleaning and improving fire safety by eliminating grease build-up at the source
  • Complete installation includes UVC lamp modules, power supply units, control interface, and safety interlocks, ensuring compliance with hygiene and environmental regulations in commercial kitchens.

Bespoke Kitchen canopies with integrated controls

  • Installation of bespoke kitchen canopies equipped with control and automation systems
  • Fan speeds automatically adjust based on real-time cooking activity.
  • Built-in alert system for operational changes or malfunctions
  • Automatic pressure balancing to maintain safe and efficient kitchen airflow
  • Custom-designed kitchen extraction system created to control odour and grease, preventing contamination and maintaining air quality standards 

Fire suppression System

  • Automatic detection and suppression of fires using wet chemical agents engineered explicitly for grease and high-heat applications
  • Seamless integration with the canopy extraction system and gas interlock units for complete kitchen safety automation
  • System activation shuts off fuel and electricity to affected zones instantly, preventing re-ignition
  • Built-in test and maintenance alerts to ensure compliance with fire safety regulations and ongoing system readiness

Dishwasher extract system

  • Designed to remove excess steam, heat, and moisture from commercial dishwashing areas 
  • Integrated moisture sensors trigger extraction based on steam levels to optimise energy use and maintain comfortable working conditions.
  • Condensation management to prevent water accumulation on surrounding surfaces

Kitchen fresh air system and associated controls

  • Ensures clean, filtered air is consistently introduced.
  • Maintains correct air pressure to prevent drafts, backflow, and energy loss
  • Temperature sensors to monitor air quality and automatically adjust airflow rates for optimal working conditions
  • Real-time monitoring, remote access, and fault alert systems

Refrigeration cold rooms and associated controls

  • High-performance refrigeration cold rooms designed for temperature-critical storage, with insulated enclosures, air-tight doors, and integrated thermal barriers 
  • Complete installation of refrigerant plan, evaporators, control panels, pipework, and monitoring systems, including temperature alarms, defrost cycles, and remote access controls.

Custom Design of all the above systems

  • Complete mechanical fit-out solution custom-designed for the project
  • Integration of digitalised technology and innovation into mechanical services 
  • A Collaborative design approach to optimise space, efficiency, and user experience.
