Why Coolrooms Matter for Your Business

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 that support businesses across a wide range of sectors.

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. We understand that each facility has unique temperature demands, workflow requirements, and compliance obligations, which is why our engineered systems provide the right balance of efficiency, accessibility, reliability, and future-proofing capabilities.

Our team carefully evaluates building layout, product turnover speed, and employee workflow to ensure ideal placement of shelving, racking, access points, and evaporators. This ensures fast temperature recovery during busy hours, reduced heat infiltration during loading, and lower operating expenses. By partnering with TIESA, you get more than a cooling space — you gain a strategic asset that protects products, supports business continuity, and enhances operational efficiency over time.

What is a Coolroom?

A coolroom is a temperature-controlled room designed to store perishable goods at a consistent temperature, typically 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. These components work together to stabilise temperature, manage airflow, and maintain ideal storage conditions for sensitive products.

Coolrooms differ 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 and regulated industries, a well-designed coolroom is not just about storage—it’s about reducing wastage, protecting inventory value, meeting food safety compliance, and achieving long-term cost savings. For businesses in hospitality, logistics, medical sectors, and agriculture, maintaining accurate temperature control is essential to preserve freshness, extend shelf life, minimise risk, and ensure customer trust.

Modern coolrooms can be equipped with automated sensors that track temperature, humidity, and door activity. These systems send instant alerts when conditions shift outside of acceptable ranges, helping businesses resolve issues before damage occurs. Many facilities combine these features with digital compliance reporting, offering accessible documentation for inspections and audits. With proper design and maintenance, a coolroom becomes a dependable, long-term asset that supports productivity and operational excellence.

Key Considerations When Designing a Coolroom

1. Drainage and Tundish Location

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. In high-volume facilities, good drainage also supports hygiene compliance, eliminating excess condensation that can compromise surfaces, insulation, and flooring. Ensuring proper drainage also reduces the risk of foul odours, moisture damage, and structural corrosion over time.

2. Power Availability

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:

  • One single-phase (240V, 10A) for the coolroom controls
  • One three-phase supply for the condensing unit

This separation ensures stability, compliance, and operational reliability. Proper electrical planning allows future expansion, simplifies servicing, and ensures the system remains functional during increased load demands. Systems with backup power capabilities, voltage protection, and surge safeguards can further enhance reliability and protect high-value inventory.

3. Fire Rating of Panels

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. Beyond insurance, choosing the right panel type contributes to longevity, enhances internal temperature stability, and improves the room’s resistance to moisture, damage, and microbial growth.

4. Load, Layout & Usage

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, racking layout, and heat loads to ensure optimum design. Proper planning also prevents warm spots, allows faster temperature recovery after door openings, and improves inventory turnover. This ensures efficiency even during peak operational periods.

Types of Coolrooms We Provide

Commercial Coolrooms

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. Compact or large, every system is engineered to withstand continuous operation, frequent door openings, and high humidity conditions common in commercial settings. These coolrooms also integrate intuitive control panels for easy operation and maintenance.

Industrial Coolrooms

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. Heavy-duty flooring, reinforced panel systems, and robust refrigeration ensure reliable performance under continuous load. Industrial clients benefit from customised layouts that support workflow efficiency, automation compatibility, and safe handling of bulk materials.

Pharmaceutical & Medical Coolrooms

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. Solutions include backup power connections, real-time monitoring, and calibrated logging systems that ensure regulatory adherence. These environments protect sensitive products from instability, degradation, and contamination.

Humidity-Controlled Coolrooms

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. These coolrooms support industries where appearance, texture, and freshness significantly influence product value and sales outcomes.
