Replacing and Installing 3 Commercial Rooftop Air Conditioners

Ice Blast Delivers Major Rooftop PAC Unit Upgrade at a Laboratory in Eight Mile Plains

In a significant commercial HVAC upgrade, Ice Blast was engaged by the laboratory in Eight Mile Plains, Queensland, to replace their ageing rooftop packaged air conditioning (PAC) unit. The project involved the complete decommissioning and removal of the existing PAC system, followed by the supply and installation of three high-performance APAC rooftop units: two 63.89kW Three Phase Horizontal Rooftop PAC Units and one 94.04kW Three Phase Horizontal Rooftop PAC Unit. The upgrade was executed with a strong focus on operational continuity, safety, and long-term energy efficiency for the client.

Project Scope and Objectives

The laboratory, which is a leading provider of analytical testing services, relies heavily on precise temperature control across various operational zones within their facility. The ageing existing PAC unit was not only becoming unreliable but was also inefficient, leading to rising maintenance costs and inconsistent climate control.

Ice Blast was commissioned to undertake a full upgrade that would improve overall cooling performance, ensure compliance with modern standards, and offer greater reliability and energy savings for the facility.

Safe Decommissioning and Removal of PAC Units

Before any new equipment could be installed, the Ice Blast team needed to safely decommission the existing rooftop PAC unit. This stage required careful planning due to the unit’s rooftop location and integration with the building’s existing mechanical systems.

The process began with the safe disconnection of power supplies and refrigerant recovery, carried out in accordance with Australian environmental and safety regulations. Once fully decommissioned, the old unit was dismantled and removed from the roof using a crane, with all waste materials responsibly disposed of or recycled where possible.

During this phase, Ice Blast also ensured minimal disruption to the laboratory’s daily operations. Temporary climate control measures were put in place as required to maintain indoor comfort for staff and equipment during the switchover.

New Equipment: Three APAC Rooftop PAC Units

With the old system removed, the Ice Blast team proceeded with the delivery and installation of three new APAC rooftop air conditioning units:

• 2 x 63.89kW APAC Three Phase Horizontal Rooftop PAC Units
  
• 1 x 94.04kW APAC Three Phase Horizontal Rooftop PAC Unit
  

These units were chosen for their robust performance, energy efficiency, and suitability for large commercial spaces like laboratories. APAC’s horizontal rooftop systems are known for their reliability, flexible design, and ease of service access, making them ideal for demanding operational environments.

Each unit features high-capacity compressors and advanced control systems designed to maintain consistent temperature levels, even under variable load conditions. The dual 63.89kW units provided a balanced approach to zoned cooling, while the single, larger 94.04kW unit offered extra power for high-demand areas.

Air Conditioner Installation and Integration

The commercial rooftop air conditioner installation required precision and coordination. A crane was used to lift each unit into place on the existing mounting structure, which was assessed and reinforced by the Ice Blast team where needed to accommodate the new equipment’s weight and configuration.

Once in position, each unit was securely fixed and connected to the building’s existing ductwork and electrical infrastructure. Ice Blast’s licensed HVAC technicians handled all refrigerant pipework, electrical cabling, and control wiring with meticulous attention to detail.

Commissioning involved:

• Thorough testing of electrical connections and phase balancing
  
• Programming and calibration of each PAC unit for optimal performance
  
• Integration with building management and control systems (where applicable)
  
• Verification of airflow, temperature control, and refrigerant pressures
  

Energy Efficiency and Performance Benefits

One of the most significant advantages of the new APAC air conditioning rooftop units is their improved energy efficiency. With modern three-phase motors and better compressor technology, the new PAC systems are designed to use significantly less energy than the previous unit, translating into lower operational costs for the laboratory.

Additionally, the improved air distribution and climate control will support the laboratory’s strict environmental requirements, helping protect sensitive equipment, materials, and test samples.

Key benefits delivered include:

• Enhanced cooling performance and system reliability
  
• Reduced noise levels due to modern fan technology
  
• Lower energy consumption and environmental impact
  
• Simplified ongoing maintenance with accessible service panels
