Get Highly Efficient, Reliable Cooling in a 42U Rack Form Factor
The harder your data center, network closet or server room works, the more it heats up, leading to inefficient operation, weakened performance and raised cooling costs. To help prevent equipment shutdowns, malfunctions and failures caused by overheating and temperature fluctuations, the SmartRack® SRCOOL33K provides a close-coupled cooling solution in a 42U rack form factor that reduces energy use, lowers operating costs and simplifies installation.
Completely Self-Contained for Simplified and Less Expensive Installation and Maintenance
The zero-maintenance SRCOOL33K with its intuitive LCD interface is easy to install and operate. You and your IT staff can install it yourself. No costly startup service, electrician or HVAC contractor is needed. A built-in evaporator eliminates condensation through the exhaust air stream, so no costly floor drain, water collection tank, external condenser, refrigerant piping, ductwork or plumbing is required.
Advanced Network Monitoring Keeps You in Touch 24/7
The pre-installed Java-free HTML5-based WEBCARDLX interface enables full remote monitoring, configuration, control and email notifications via secure web browser, SNMP, telnet or SSH. It supports 10/100 Mbps auto-sensing for optimum communication with an Ethernet network.
Energy-Saving Features Meant to Save You Money
A row-based airflow path maximizes hot-aisle/cold-aisle efficiency and cooling predictability by delivering cold air high in the cold aisle and removing hot air in the hot aisle. The SRCOOL33K promotes temperature uniformity from 1U to 42U, allowing your equipment to perform at its peak and reduce power consumption and operating costs, and features an AC-driven rotary compressor.
One-Year Warranty and Environmentally Responsible Design
The SRCOOL33K comes with a one-year warranty. It’s manufactured in compliance with strict RoHS specifications and uses eco-friendly R410a refrigerant.

Questions & Answers

Excessive heat can damage servers, reducing the life of equipment and potentially causing an unexpected shutdown. Humidity problems can also accompany excessive heat. High humidity can cause condensation and lead to the accumulation of dust on components. Low humidity can cause electrostatic discharge (ESD).

For newer IT equipment, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends an operating temperature of 64°F to 81°F (18°C to 27°C), and a relative humidity (RH) of 60 percent.
