Rittal Cooling Units for Quiet Environments

Rittal’s ‘Blue e’ cooling units are usually found controlling the temperature within enclosures in workshops or on shop floors in the industrial sector where noise level is largely irrelevant as they cannot be heard above other equipment in these noisy environments.
In situations such as laboratories, offices or other more peaceful areas where cooling is required, Rittal’s TopTherm ‘Blue e’ roof-mounted cooling unit range successfully provide cooling where excessive noise would be an irritant to personnel working close to an enclosure.

With nominal outputs of 1.1 kW, Rittal roof-mounted cooling units for office applications offer viable solutions when it may have been assumed they would simply be too noisy.

Rittal’s ‘Blue e’ cooling units benefit from the intelligent and targeted use of energy, electronically commutated (EC) fan technology and are proven to achieve energy savings of up to 45%. Nano-coated condenser coils negate the need for filters and an integrated electric condensate evaporator maintains an efficient supply of cooling for longer periods of time extending maintenance intervals.

Proven protection for data centres

Rittal has updated the DET-AC III product family, comprising the DET-AC III Master fire alarm and extinguisher system, the complementary DET-AC III Slave unit and the EFD III early fire detection solution. All three are available in the form of 19’’ slide-in racks.

Significant enhancements have been made to the DET-AC III Master. The system now features a CAN bus interface for direct integration with the Rittal CMC (Computer Multi Control) III monitoring solution. This provides administrators with much more detailed information on the status of installations and incoming alerts.

A new USB interface greatly simplifies service and maintenance of the DET-AC III. This allows service technicians to view information on operational status and events, modify configurations, reset service intervals, or install new firmware from a laptop, without opening the enclosure.

Taking up one U in a 19’’ rack featuring a two-stage smoke extraction system, two highly sensitive optical sensors detect even the smallest smoke particles at very early stages and can sound an alarm from 0.25 per cent obscuration per meter. If the first sensor detects smoke aerosols, a pre-alarm is issued. If the second sensor also detects smoke, the main alarm is triggered and the extinguisher is activated.

Using the 3M NOVEC™ 1230 fire suppression solution, the system was the first in its class to successfully pass comprehensive VdS testing. It is environmentally friendly, does not conduct electricity and does not damage IT equipment.

All systems are available for immediate shipment and replace previous versions.

Rittal provide state of art technology for flooded airflow cooling solution

Rittal have recently provided high quality TS IT server racks, with a customised chimney venting solution, for data centre provider Datum who required cost effective cooling technology when developing their flagship Farnborough facility.

After research Rittal’s roof mounted chimney module, a one piece duct assembly on top of the TS IT enclosure for airflow management, was found to work perfectly with the patented ecofris cooling solution from Keysource.
A reliable passive system requiring no fans or electrical connections, the chimney module permits the hot and cold air to be separated efficiently, eliminating the hot aisle, as the exhausted heat is contained within the chimney system.

Utilising Rittal chimney modules allowed the cooling system in the room to work to its’ full potential, delivering a PUE of 1.2 or less, achievable even with a partial load.

Dominic Phillips, MD of Datum said “The result is a complete alignment of our energy efficient goals with those of our clients delivering a reduced carbon footprint and cost”.

Rittal’s Efficient cooling solutions lower PUE for Node4

Utilising the latest in energy efficient cooling technonology from Rittal has dramatically lowered PUE at Node4’s latest datacentre at Northampton.

Space for future growth, using the latetst in energy efficient technology, is key to the long term strategy for the site. Working closely with Rittal, Node4 were able to maximise IT floor space using CoolWall technlogy, Cold Aisle Containment and Rittal’s TS IT racks, along with managed Power Distribution Units.

CoolWall was selected over traditional CRAC based cooling as the larger coils increased capacity of cooling whilst driving down running costs at elevated temperatures.

Designed to dramatically reduce PUE and improve the overall efficiency of the data centre, the system offered a further benefit of separate fans for ease of maintenance.

Rik Williams of Node4 said “Working in partnership with Rittal we were able to utilise their technical expertise and speed of supply to deliver the most cost effective solution”.

Demand based automatic fan speed control from Rittal

A new fan speed control sensor for Rittal’s TopTherm fan-and-filter units is now available. This handy and compact device, which is compatible with the larger models in the range of electronically commutated (EC) TopTherm fan-and-filter units, automatically adjusts the fan speed in response to changes in temperature inside the enclosure.

Providing a simple and cost effective solution to the problem of fan-and-filter units running continuously, even when not required as the panel temperature is already at an acceptable level, the sensor will help to reduce energy consumption and consequently, running costs.
With a fixed setpoint of 35 °C, the device provides continuous control with fan speeds varying linearly between 10 % at 20 °C and 100 % at 35 °C. No additional power supply is required as the sensor takes a 10 V DC feed from the fan-and-filter unit itself.

Larger TopTherm fan-and-filter units with EC motors from Rittal, accept a 0 to 10 V DC or PWM control signal and can be controlled using a programmable logic controller (PLC). A tachometer signal output to monitor fan speed and operating conditions is included, to alert users immediately should any faults or failures occur.

Rittal’s simple fan-and-filter unit is an innovative product with integrated energy efficient control, performance monitoring and sensor for speed control to achieve the best results.

Rittal and the IEC 61439 Standard

Design engineers should be aware that the the IEC 61439 switchgear and controlgear systems standard will take effect from November 2014. This standard also applies to wall mounted control panels as well as floor standing power distribution assemblies.

For the smaller control panels with current ratings of below 630A, the ratings of the busbar system and controlgear components must be de-rated in line with the standard. A key feature of the standard is the calculation of the maximum internal temperature of enclosure.
To assist the design engineer Rittal can supply Therm software that will calculate internal temperature and Power Engineering software that can design the panel layout in line with the standards.

For further information regarding Rittal solutions and assistance with compliance to IEC 61439, please contact Mark Guest mguest@rittal.co.uk or, to receive a free copy of the guide book, please use powerdistribution@rittal.co.uk
