Rittal Blue e+ Cooling Unit 1500W

The Rittal Blue e+ Cooling Unit 1500W (model 3385.540) is Rittal's most energy-efficient enclosure climate control solution, representing a fundamental departure from conventional compressor-based cooling. The Blue e+ combines a conventional vapour-compression refrigeration circuit with an innovative heat pipe technology that eliminates compressor operation entirely during periods of moderate ambient temperature — a breakthrough that reduces energy consumption by up to 75% compared to traditional enclosure air conditioners. The 3385.540 is rated at 1500 W cooling capacity at L35/L35 conditions (35°C ambient, 35°C internal set point), making it ideal for enclosures housing drives, power supplies, PLC hardware, and other heat-generating components that must be maintained below 35°C even during Saudi Arabia's summer months when outdoor ambient temperatures routinely exceed 48°C.

The Blue e+ 3385.540's unique hybrid cooling mode selects automatically between heat pipe natural convection and compressor-assisted vapour compression depending on the difference between internal and external temperatures. When the ambient is only moderately warm — such as in air-conditioned control rooms or at night — the heat pipe does all the work with zero compressor energy. Only when the temperature differential demands it does the compressor engage, and even then it modulates via an integrated EC fan and variable-speed compressor rather than cycling on/off, which eliminates the energy waste and compressor wear associated with conventional thermostat-controlled coolers. The result is a cooling unit that in Saudi Arabian conditions — with a typical annual average ambient of 35°C and peak summer of 48°C — delivers total cost of ownership (TCO) savings that recover the premium price over a conventional cooler within 18 to 24 months.

The relevance of the Blue e+ to Saudi Arabia's industrial landscape is profound. At ARAMCO's Dhahran headquarters complex, SABIC's Jubail petrochemical plants, and the extensive NEOM smart-city infrastructure, thousands of electrical enclosures must maintain controlled internal temperatures to protect sensitive electronics. Saudi Energy Company (SEC) and SEC-regulated industrial customers face rising electricity costs and mandatory energy efficiency reporting under Saudi Arabia's National Energy Efficiency Program (NEEP). The Blue e+ directly addresses both concerns: its EER (Energy Efficiency Ratio) of over 4.0 at standard conditions makes it one of the most efficient enclosure coolers on the market, and its integrated NFC-enabled monitoring interface enables remote performance reporting via Rittal's RiDiag smart diagnostic tool. For Vision 2030 infrastructure projects targeting LEED Gold or local sustainability certifications, specifying Blue e+ cooling units provides documented energy performance data for green building submissions.

Razz Middle East supplies the Blue e+ 1500W unit and provides full application support including thermal load calculations for specific panel configurations, ambient condition modelling for Saudi sites, and on-site commissioning. Our engineers are trained to configure the Blue e+ monitoring interface for integration with Rittal's CMC III panel monitoring system, enabling centralized visibility of cooling unit performance across large industrial facilities in Riyadh, Dammam, Jubail, Jeddah, and Yanbu.
