Keep Your Cool: Smarter Enclosure Cooling for NZ Food & Beverage Operations

As Warmer Months Approach, Smart Cooling Becomes Essential

Rising temperatures can place added strain on industrial equipment, especially in food and beverage environments where uptime, hygiene, and temperature control are critical. Overheating can lead to costly downtime, equipment failure, and compliance risks.

Rittal’s Blue e+ fan-and-filter units are purpose-built to meet these challenges in Australia and New Zealand’s food and beverage industry. Designed for energy efficiency and reliable performance in hygiene-sensitive environments, they offer:

  • Up to 60% energy savings via advanced EC motor technology
  • Automated fault detection to prevent unexpected failures
  • Remote monitoring for better visibility and proactive maintenance
  • Emergency cooling mode that responds instantly to temperature spikes

With high airflow, smart IoT integration, and simplified maintenance, Blue e+ is ideal for applications like dairy processing, brewing, and temperature-controlled production lines.

Key Benefits of Rittal’s Blue e+ Fan-and-Filter Units

Higher Airflow for Greater Efficiency
Pleated filters increase airflow by up to 40% compared to traditional chopped-fibre options, delivering efficient cooling that reduces stress on electrical components. Combined with diagonal fan technology, the system maintains consistent temperatures across the entire enclosure, minimising hot spots and enhancing overall reliability in temperature-sensitive operations.

Modular Design for Simple Installation, Fast, Hygienic Installation and Maintenance 
Blue e+ fan-and-filter units are designed for quick, tool-free installation with a bayonet fitting and reversible airflow for flexible setup in high-moisture or dust-prone areas. Routine maintenance is easy thanks to a simple grille-opening system and clip-lock design, allowing fast filter changes while supporting food industry compliance.

Advanced IoT Capabilities for Smart Cooling
Modern food processing facilities require real-time monitoring to ensure optimal performance and compliance with industry standards. The Blue e+ EC fan-and-filter units incorporate IoT-enabled technology, allowing operators to track system performance remotely and take proactive maintenance measures before issues arise.

Enhanced Protection with the Blue e+ Fan and Filter with Hose-Proof Hood

Food and beverage processing environments demand higher protection against dust, moisture, and cleaning processes. The Blue e+ Fan and Filter with Hose-Proof Hood accessory increases the IP rating from IP54 to IP56, offering superior protection against water ingress and airborne contaminants.

Key benefits include:

  • Increased durability while maintaining efficient cooling performance
  • Minimal impact on airflow, ensuring continuous operation
  • Enhanced protection for sensitive electronics, extending equipment lifespan

This small adjustment significantly improves the resilience of enclosure cooling systems, particularly in applications where equipment is exposed to frequent washdowns and high humidity.

Predictive Maintenance and Long-Term Cost Savings

Predictive maintenance is a critical factor in reducing downtime and operational costs in food and beverage processing. The Blue e+ fan-and-filter units provide real-time monitoring of system performance, allowing operators to identify and address issues before they impact production.

An automatic filter cleaning function extends filter lifespan by up to 20% by periodically reversing the fan rotation to dislodge fine dust particles. This reduces maintenance frequency, minimising the need for manual interventions and associated labour costs, ensuring compliance with food safety standards while reducing the risk of contamination.

Rittal’s Blue e+ fan-and-filter units provide a high-performance enclosure cooling solution, ensuring efficient heat removal, easy installation, and long-term reliability. With IoT-enabled monitoring, enhanced protection options, and simplified maintenance, these units help the food and beverage industry reduce energy costs and optimise equipment performance.
