HVAC-R Systems

We provide end-to-end HVAC-R services, including system design, installation, maintenance and repair. Each solution is developed to suit the specific operating requirements of the site or vessel, whether that involves a commercial facility, industrial process or marine application.

With in-house design capability, the team works closely with clients to engineer systems that are efficient, durable and aligned to how the environment actually operates.

HVAC-R System Design & Engineering

We provide in-house system design capabilities, allowing solutions to be developed specifically for the operating environment – whether that’s a commercial facility, industrial process, or marine vessel. Systems are engineered to perform reliably in harsh conditions, where durability and precision are critical.

Capabilities include:

• Custom system design for air conditioning and refrigeration
• Engineering systems to suit spatial, operational and environmental constraints
• Designing for marine conditions including vibration, salt exposure and confined spaces
• Selection of appropriate equipment based on performance, efficiency and durability

Rather than working from off-the-shelf layouts, systems are engineered around how the site or vessel actually operates, improving efficiency and reliability over time.

Marine HVAC & Refrigeration

ARA Marine provides complete lifecycle support for marine HVAC and refrigeration systems, from engineering and installation through to ongoing maintenance and rapid breakdown response. Operating in some of the most challenging environments, Cooltech’s solutions are designed and engineering for:

• Extreme conditions, including vibration, corrosion, space constraints and variable load demands
• Compliance with marine, defence and classification standards, supporting safety, regulatory and operational requirements
• Diverse vessel classes, from naval and commercial fleets to high-end superyachts and industrial platforms
• Reducing operating costs while maintaining performance and comfort

Chilled Water & Refrigeration Solutions

Specialising in advanced chilled water and cooling systems, Cooltech designs and delivers tailored solutions for marine environments where reliability and efficiency are paramount. They offer:

• Custom‑engineered chilled water and cooling systems
• Marine‑specific designs for performance, efficiency and longevity
• Full lifecycle support from design through to maintenance

From initial system design to installation and long‑term maintenance, each solution is engineered to deliver consistent temperature control, energy efficiency and dependable operation across a wide range of applications.

HVAC & Duct Sanitisation

To support system performance, hygiene and compliance, we offer comprehensive HVAC and duct sanitisation services. This includes system flushing, hygiene remediation and preventative maintenance designed to safeguard air quality and protect critical cooling infrastructure. The result is:

• Comprehensive duct and HVAC hygiene services
• System flushing, cleaning and remediation
• Improved air quality and system performance
• Supports regulatory compliance and operational safety

Installation & Commissioning

The business delivers complete installation services, covering new builds, retrofits and system upgrades across commercial, industrial and marine environments. Projects are delivered end-to-end, ensuring systems are installed correctly, tested properly, and performing as intended.

Capabilities include:

• Installation of commercial and industrial air conditioning systems
• Refrigeration system setup, including cool rooms and process cooling
• Marine HVAC-R installation for vessels of varying sizes
• System commissioning and performance testing
• Integration with existing infrastructure

Maintenance & Preventive Servicing

Ongoing maintenance is a core part of the service offering, ensuring systems remain reliable and efficient under continuous use. Structured maintenance reduces the likelihood of costly failures, extends equipment life, and ensures systems operate at optimal performance.

Capabilities include:

• Scheduled maintenance programs
• System inspections and performance checks
• Preventive servicing to reduce downtime
• Compliance and operational checks for critical systems

Breakdown & Repair Services
