In today’s commercial and industrial environments, coolrooms are the backbone of reliable food storage, pharmaceutical preservation, and temperature-controlled logistics. Whether you run a restaurant, a food processing plant, a supermarket, or a pharmaceutical warehouse, maintaining precise temperature and humidity levels is critical to safety, compliance, and efficiency.
At TIESA, we specialise in designing, building, and maintaining energy-smart coolrooms that keep your operations running smoothly. Based in Sydney, our team brings together decades of refrigeration engineering and project management expertise to deliver tailored coolroom solutions.
Unlike off-the-shelf cold storage, our custom-engineered coolrooms are designed around your product load, floor space, energy efficiency requirements, and long-term maintenance needs. From small walk-in coolrooms to large-scale warehouse cold storage, TIESA ensures every installation is robust, reliable, and built for maximum performance.
A coolroom is a temperature-controlled room designed to store perishable goods at a consistent temperature, usually between 0°C and 10°C. Depending on the application, it may also include humidity control systems, fire-rated insulated panels, floor heating, and advanced refrigeration controls.
Coolrooms are different from freezers, which operate at sub-zero temperatures, but both share the same goal: protecting product integrity while optimising energy efficiency. In Sydney’s competitive industries, a well-designed coolroom is not just about storage—it’s about reducing wastage, meeting food safety compliance, and achieving long-term cost savings.
Effective drainage is critical. Coolrooms rely on gravity-fed drains, so the tundish must be located as close as possible to the evaporator. If no direct drain is available, a condensate pump is required. Proper drainage prevents water pooling, bacterial growth, and safety hazards.
Electrical supply must be planned carefully. The coolroom system is controlled separately from the condensing unit, and larger systems (over 3000W cooling capacity) may require two sub mains:
This separation ensures stability, compliance, and operational reliability.
Not all insulated panels are equal. EPS, PIR, and X-flam panels each have different fire ratings, insurance implications, and durability factors. Businesses covered under FM Global insurance should confirm their panel requirements early in the design stage to avoid costly retrofits.
A coolroom’s efficiency depends on product load, racking, and usage cycles. A poorly designed airflow system or undersized refrigeration unit can lead to temperature fluctuations, product spoilage, and higher energy bills. TIESA engineers carefully model airflow, pipe routing, and heat loads to ensure optimum design.
Perfect for cafes, restaurants, and supermarkets, our commercial coolrooms are designed for frequent access and fast temperature recovery. We offer durable insulated panels, rapid roller doors, and energy-efficient refrigeration units that minimise running costs.
For large-scale storage and food processing, we design industrial-grade coolrooms capable of handling high product volumes, pallet racking, and integrated conveyor systems. These rooms are built with scalability in mind, allowing for future expansion.
Strict compliance with GMP (Good Manufacturing Practice) and TGA standards requires precise temperature and humidity control. TIESA designs pharmaceutical-grade coolrooms for hospitals, laboratories, and vaccine storage facilities.
Moisture management is critical for products such as fresh produce, mushrooms, and pharmaceuticals. Our dehumidification systems ensure optimal humidity levels, protecting your inventory from mould, condensation, and spoilage.
At TIESA, we don’t just build coolrooms—we build energy-smart systems. Rising electricity costs in Sydney mean businesses can no longer afford inefficient cold storage. Our engineers apply thermodynamic modelling, airflow simulations, and smart control systems to optimise performance.
Key benefits of TIESA coolrooms include:
Designing and installing a coolroom is a complex engineering process. At TIESA, we simplify it into four stages:
Our project management team ensures minimal disruption to your operations and strict adherence to deadlines.
A coolroom is a significant investment, and ongoing maintenance is essential to protect it. TIESA provides preventive maintenance, emergency repairs, and 24/7 support. With Simpro client portals and asset tracking, you’ll have complete visibility of your system’s performance and service history.
Regular maintenance prevents:
When you choose TIESA, you’re choosing a partner who understands that temperature control is mission critical for your business.
1. How long does it take to build a coolroom?
A standard commercial coolroom can be completed within 2–3 weeks. Large-scale industrial projects may take several months depending on size and complexity.
2. What temperature range can coolrooms operate in?
Typically between 0°C and 10°C, but we customise systems for specific industries, including produce, meat, and pharmaceuticals.
3. Do I need council approval for a new coolroom?
Some projects require development approval, especially if structural changes are involved. TIESA assists with compliance and documentation.
4. How often should my coolroom be serviced?
We recommend quarterly preventive maintenance to ensure efficiency, compliance, and extended equipment life.
If you’re planning a new coolroom, upgrading an old system, or need reliable maintenance support, contact TIESA today. We’ll help you design and maintain a system that is energy-efficient, reliable, and built to last.
