he Murelle Revolution 30 is the first completely integrated boiler and heat pump in a single cased product. Using an ErP A++ 30 kW Murelle boiler


and completely sealed 4kW output heat pump, the Murelle Revolution 30 is a single compact unit that can be installed by any registered Gas Safe installer in a single installation process, without requiring an additional Fgasregistered installer to be present. The unique Murelle Revolution 30 should be installed


inside and hung on the wall like a conventional boiler. The Revolution provides heat and hot water, achieving an average seasonal heating performance of 134%, granting A++ energy efficiency, according to the ErP Ecodesign Regulation.


How it works The boiler and heat pump work in tandem, with the heat pump operating first, as this makes the largest contribution to the Murelle Revolution’s energy efficiency. When the external temperature is higher than its minimum set value

(default 7°C) the heat pump and the boiler will be activated in quick succession. When the set point is reached, the boiler will start to adjust power until the heat requirement is attained and then both of the generators will be extinguished.


If the external


temperature is higher than 7°C (value can be reset), only the heat pump will be activated. The boiler will be activated only when the desired temperature is not achieved by the heat pump on its own.


Technical description Heat carrier fluid receives heat from air taken from outside into the main evaporator. Once inside the evaporator, this heat carrier fluid comes into contact with exhaust gases from the boiler. The compressor compresses the fluid and the heat is transferred via the platetype condenser/exchanger to the water returning from the central heating system. The boiler’s heat exchanger integrates the residual heating requirements.

meter can all be fitted with various low, medium and highfrequency pulse outputs. All devices can be connected to various electronic ancillary devices such as Electronic Volume Converters (EVC’s) remote ATEX flow displays, data loggers and data telemetry devices for monitoring and reporting. The MRM rotary displacement gas flow meter is designed for


fiscal metering of natural gas and is approved according to the European requirements of EN12480, MID (2004/22/EG) and OIML R1371 & 2: 2012. The MRM rotary displacement gas meter is suitable to be installed in hazardous areas of Category 2 (Zone 1) II 2 G c IIC T4 X. The MRM rotary displacement gas meter is suitable for the following gases: Natural gas, town gas, propane, butane, ethylene, air, nitrogen, with further gases on request. Rotary gas meters are characterized by their very compact design and high accuracy. The MRM rotary meter requires no

inlet or outlet straight pipe lengths or flow conditioning and is insensitive to severe gas flow fluctuations (discontinuous operation). The rotary meters MRM are manufactured with large measurement ranges due to the precision machining of the parts and a very reproducible assembly process. The standard calibrated measurement range for the MRM is 1:50. Extended measurement ranges up to 1:200 are optionally available according to approved and certified measurement ranges as shown in the table. The MRM rotary gas meters show very stable and reproducible


measurement results. The design of the housings and pressure containing parts has been optimized especially for outstanding operation, even under challenging torsional and bending stresses. The meters can withstand more than twice the specified torsional and bending stresses after installation as defined in EN 12480. The lifetime durability of the MRM rotary gas meter is very


stable due to the large dimensioned high precision ball bearings “Made in Germany” along with the high precision machining of the body and all moving parts. After machining all Aluminium parts are hard anodized for reduced friction and higher resistance to mechanical wear and tear or chemical attack. Utilizing the LF of HF pulser (reed contact) the volume pulse output sensors allow for remote monitoring, data recording and linking with Building Management Systems (BMS) as well as with gas volume correctors (EVC's) and our ATEX telemetry systems.

40 BUILDING SERVICES & ENVIRONMENTAL ENGINEER SEPTEMBER 2019


Port, Formula Services Premier Truck Stop offers customers top class facilities, including a free fitness room along with superb lounge/relaxation areas with free massage chairs, Sky sports and Xbox usage, to shower, laundry and catering facilities and even the use of free bicycles to get out and about. A key part of its success has been its


onsite security as Gerry Graham, General Manager of Formula Services, states: “Security is vital to our business and our clients/customers, who all carry materials/items of value. On our new website we heavily promote our site security (36 Cameras, Manned Security Guards, ANPR) as this is what hauliers/customers require and, I personally believe, insurance companies also want this level of security. I believe that along with our superb facilities, the security measures that we have in place most definitely contributed towards our winning of the Truck Stop of the Year award and our accreditation with TAPA (LEVEL 3 PSR). I believe we will also start to see additional benefits as we enter 2019.” STANLEY Security designed and


installed a 36 camera CCTV system with six monitors. A mostly external system to protect the site from unwanted visitors, static cameras were used for perimeter detection and Pan Tilt and Zoom cameras deployed in key locations.

A key challenge involved utilising the


existing onsite cabling, which meant thinking outside of the box. A solution was found by STANLEY, involving Dahua extenders to boost the signal to the furthest points then powering the cameras via switches at the bases of the camera towers. This enabled the cable to be used without compromising the quality of the CCTV system. Gerry based his decision to award


this contract to STANLEY Security on his previous experiences when looking at site security. “I also looked at the site’s history with two to three previous security installers and basically went with what I believed to be the best option for Formula; this included back up support/maintenance etc.” Formula Services is clearly pleased


with the results as Gerry comments: “Having spoken with the security staff who operate the equipment they believe the clarity of the pictures, along with the easy to use controls, are the main benefits. Our site customers are also impressed with the system/cameras.”
