Testo launches new multi-function<br />
instrument for ventilation and air<br />
conditioning engineers<br />
The new Testo 435 has been designed to provide<br />
air conditioning engineers with a single<br />
instrument that can measure all of the key<br />
parameters needed to determine Indoor Air<br />
Quality (IAQ) and the efficient installation and<br />
maintenance of Ventilation & Air Conditioning<br />
(VAC) systems.<br />
In addition to air velocity, the Testo 435 can be<br />
used to measure CO2, relative humidity and air<br />
temperature to ensure conditions <strong>are</strong> at the correct<br />
level and to indicate whether air conditioning<br />
systems <strong>are</strong> working at optimum levels. A<br />
range of thermal probes, vane probes and Pitot<br />
tubes <strong>are</strong> available for the Testo 435 to allow<br />
engineers to take measurements of air flow at<br />
various points in a building. Also available <strong>are</strong> a<br />
range of probes to measure absolute pressure,<br />
comfort level, lux and surface temperature -<br />
making the Testo 435 a truly multi-functional<br />
instrument.<br />
As well as cable connected probes, the Testo<br />
435 can also be used with a range of wireless<br />
probe that remove problems such as hindrance<br />
during measurement and potential damage to<br />
Jasun Filtration’s<br />
range of Filbox<br />
housings hold any<br />
configuration of filter<br />
probe cables. The instrument is easily upgraded<br />
with an optional module and can then be used<br />
with wire probes to measure temperature and<br />
(in some models) humidity.<br />
The Testo 435 is designed for ease of use, with<br />
easy to follow menus. The 2 advanced models<br />
(Testo 435-2 and Testo 435-4) offer users the<br />
ability to allocate measured values to measurement<br />
locations. These instruments also offer the<br />
ability to switch between 2 User Profiles: Duct<br />
Measurement and IAQ.<br />
The Testo 435 is a robust instrument that is both<br />
easy to use and of robust construction. For<br />
example, the housing material (IP 54) offers<br />
built-in protection against knocks and jars and<br />
the large illuminated display is set back in the<br />
housing to offer protection. To assist everyday<br />
use the instrument features a carrying strap and<br />
magnets on the back panel for attachment at<br />
the measuring location.<br />
The Testo 435 offers users 2 convenient documentation<br />
options; print out on-site to the<br />
optional Testo printer or analysis and documentation<br />
on a PC. The Testo 435-2 and 435-4 mod-<br />
The UK’s oldest independent filter<br />
manufacturer, Jasun<br />
Filtration, is producing a state-ofthe-art<br />
range of Filbox housings<br />
able to hold all air filters, in any<br />
configuration. Designed for both<br />
internal and external siting the<br />
housings <strong>are</strong> manufactured using<br />
30mm extruded, anodised, low<br />
weight aluminium framework<br />
with plastic coated steel panels<br />
making them light but strong. Also<br />
included <strong>are</strong> vice action flush<br />
locks, which ensure a 100% air<br />
seal; plastic grab handles and an<br />
internal flange supplied and fitted<br />
with insert nuts, pre-drilled to<br />
match with mezz flanges.<br />
The Filbox filter housings <strong>are</strong> available<br />
in various models in a wide<br />
range of sizes and dimensions.<br />
They <strong>are</strong> capable of holding a single<br />
row of bag filters of varying<br />
thickness ranging from 95mm to<br />
750mm and can be purchased prefiltered<br />
with a row of panel filters.<br />
Jasun Filtration also manufactures<br />
a range of Filbox housings that <strong>are</strong><br />
designed to hold discarb units up to<br />
600mm and a fine RP rigid bag filter,<br />
which acts as a smoke filter for<br />
catering applications.<br />
The filbox can be supplied as bolt<br />
together modules if access to the<br />
installation space is limited, and<br />
Jasun Filtration can even assemble<br />
these boxes onsite if needed.<br />
For buildings requiring high efficiency<br />
filtration in a very compact<br />
space, Jasun Filtration’s EcoBox<br />
incorporates three advanced filter<br />
technologies for outstandingly high<br />
efficient filtration performance.<br />
These <strong>are</strong> pre-filters, fine filters<br />
and absorbers (for odours and<br />
fumes). The EcoBox is appropriate<br />
for external and internal installation<br />
and is capable of handling air<br />
volumes ranging from 850m3/hr to<br />
60,000m3/hr. Suitable for a range<br />
of applications requiring protection<br />
from soot, dust, oil mists and bacteria,<br />
the Ecobox is ideal for commercial<br />
Kitchen Exhausts, and for<br />
use in the air conditioning of clean<br />
rooms, museums, archives, computer<br />
rooms, medical and food<br />
preparation applications.<br />

The Maxxflo stainless<br />
steel condensing<br />
storage water heater<br />
from Andrews<br />
Reader Reply No.: 84065<br />
Andrews Water Heaters introduced<br />
for 2005 the Maxxflo stainless<br />
steel, high efficiency condensing<br />
storage water heater,<br />
designed to meet the requirements<br />
of today’s energy efficient<br />
market. This latest addition to<br />
the Andrews product portfolio is<br />
in line with the demands of the<br />
new Building Regulations Part L2.<br />
It is expected to take its place<br />
alongside the Andrews R300 condensing<br />
non-storage water heater<br />
range in the Government’s<br />
Enhanced Capital Allowance (ECA)<br />
scheme.<br />
With the heating industry’s move to<br />
condensing boilers it is obvious that<br />
clients will expect water heating<br />
equipment to also be condensing.<br />
Andrews has therefore taken steps<br />
to extend their range of products<br />
utilising this technology.<br />
The new Maxxflo range of condensing<br />
storage water heaters has tank<br />
options of 200 and 300 litres capacity<br />
each with four output sizes from<br />
30 to 120kW. The high efficiency<br />
stainless steel heat exchangers,<br />
numbering up to 4 depending on<br />
output, pre-mix modulating gas<br />
burners and stainless steel tank<br />
design allow the heater to generate<br />
hot water in the condensing mode<br />
up to 80% of the tank volume, producing<br />
a nett efficiency of 109%.<br />
This will provide numerous solutions<br />
in commercial and industrial<br />
applications where the storage<br />
type of condensing water<br />
heater is preferred. Furthermore,<br />
the small footprint of the Maxxflo<br />
and its multiple flue options enable<br />
installation in unusually problematical<br />
locations.<br />
The stainless steel tank has a single<br />
bottom drain, large clean out opening<br />
and a built-in anti-legionella<br />
feature. The cold water from the<br />
base of the tank is fed into the<br />
externally mounted heat exchangers<br />
and fed to the top of the tank.<br />
Therefore, hot water is available<br />
instantaneously. The Maxxflo<br />
heater temperature can be set<br />
between 40 and 70ºC. A digital<br />
electronic controller operates the<br />
pre-mix fully modulating gas burners<br />
fitted to each of the heater<br />
modules. Reader Reply No.: 84064<br />
