Air rotation ‐ the thermally efficient solution to warehouse heating
A R
EHAU has launched NEXUS, the world’s first system for hot tapping PE‐Xa district heating networks.
REHAU NEXUS makes it possible to
retrospectively extend an existing heat network or add a ventilation or measuring point to a district heating system using REHAU orange PE‐Xa pipes. In the past, hot tapping was only possible with polymer pipes in cold water and gas mains and with steel district heating pipes. With REHAU NEXUS, expansions can be
carried out during operation and under pressure without disrupting the supply, making retrospective connections up to 80 per cent quicker. And because installers only need half the installation trench space compared to conventional squeeze‐off techniques, NEXUS can save up to 50 per cent on civil costs.
When dealing with hot water, safety is
paramount. That’s why NEXUS has been designed with a unique 3D silicone seal, which fits perfectly around the pipe and offers exceptional durability, even in temperature malfunctions up to 110°C. NEXUS’ Teflon
coated clamps are also designed for maximum temperature resistance and safety. REHAU also secured TÜV certification for its use with their orange PE‐Xa pipes to prove the highest levels of reliability. Suitable for use on RAUVITHERM and
RAUTHERMEX PE‐Xa pipe systems – both underground and in the plant room – NEXUS is manufactured in accordance with EN15632 and has a minimum lifetime of 30 years, thanks to its corrosion‐resistant design. Steve Richmond from REHAU said: “With
the increasing demand for polymer heat networks, there was a real need in the market for a system which would allow for the hot tapping of PE‐Xa pipes, so our designers set about making a product which would solve this problem for our clients. NEXUS works effortlessly with other REHAU products, like our polymer pipes, fittings and couplings, so installers can come to us for a complete, co‐ ordinated district heating system. Training is also available to ensure a perfect fit every time.”

It is designed for receiving and transmitting data from multiple 1.5mA meter loads utilising the M‐Bus protocol, and its small footprint and connection capacity for 3‐250 M‐Bus slave devices ensures it helps to meet the demand for better energy control.
ynapsys Solutions has launched the SIPslice M‐Bus Level Converter which provides an easy interface between third party M‐Bus meters and any
Scheme for the design of the courses. The manufacturer has seen an upswing in demand for its training as specifiers and engineers alike have switched on to the energy saving benefits of the A‐ rated Rinnai Infinity range. The comprehensive engineer training courses for 2017 includes nine modules: Rinnai product overview; Continuous flow and the future of water heating; Intermediate water heater; Continuous flow ‐ Excellence in design; Service and fault diagnostics (Water heaters); Service and fault diagnostics (Energy saver warm air units); Understanding ACOP L8 and hot water system design; Maximising renewable gain in hot water design; and, Continuous flow as an innovative method of satisfying energy and regulatory demands.

communications via RS232 and RS485 in applications where there is a requirement for data transfer over longer distances. Matt Gardner of Synapsys Solutions said: “The increase
in the costs of running a commercial building has led to a demand for more information and a need to utilise the information which is provided by a building. “The SIPslice M‐Bus Level Converter meets this need by allowing different metering and control solutions to communicate through a simple interface to make an effective contribution to a reduction in energy usage.”

s warm air rises, cold air falls – a well known fact. In large high bay buildings
the effect is exaggerated, with much valuable warmth heading into the roof space where it is trapped leading to cold zones at floor level. Faced with high level heat stratification and increasing energy costs, what options are available for the project consultant and specifier? In tall buildings, heat losses
can be increased by around 20%, adding to the country’s carbon burden unless an adequate means of de‐stratification is designed into any high bay heating system. One solution is to install high level de‐ stratification fans, forcing the air back down to lower levels, but installation and maintenance costs will be high, especially as working at height becomes more expensive. An alternative, simple to
install, economical and fuel efficient system has been developed that uses first physical principles to keep warm air gently circulating, maintaining constant comfort temperatures without the need for additional
In the event additional heat is
required, the pre‐mixed air passing through the unit is tempered via an indirect high efficiency gas fired heat exchanger. The burners are capable of a 4:1 modulation to ensure the discharge air is only slightly heated to maintain the space at exactly the right temperature without excess heat stratification or localised overheating. Heat is distributed evenly, both horizontally and vertically all this is achieved without costly ductwork or de‐ stratification fans, reducing installation costs to a minimum. The system is economical to run on natural gas or LPG. A recent temperature monitoring exercise in a 12m high, 16000m2 warehouse, serviced by 3 air rotation units showed only a 2oC temperature gradient between 1.5m and 11.5m levels, proving the effectiveness of the system. A custom designed system
requires few heaters and siting them at floor level reduces maintenance requirements. Installation is fast and simple.

costly high level equipment.. An air rotation heating system
works in a completely different way from most other warm air heating systems. A high airflow, low air velocity unit positioned at floor level draws in cool air at floor level and discharges it at high level across the roof space. The units “rotate” the cool air normally located at floor level, and mixes it with the warmer high level air causing it to fall and be drawn back down to low level by the constant air re‐ circulation. The system has minimal
operator involvement, being fully automatic, constantly modulating to maintain the temperature at a pre‐set level with no perceptible air movement.
Since the units incorporate robust, low noise, heavy duty fans running at relatively low speeds life expectancy is considerably increased, this further reduces overall life cycle costs. Air rotation makes simple
work of keeping large high bay buildings warm whilst providing the ideal solution for energy and environmentally conscious consultants, specifiers and building owners. Reliability, quality, financial return, long‐ term energy savings and reduced carbon emissions – all in one straightforward system configured differently to produce remarkable results.
