Aermec’s extended
chiller range
Aermec’s NRC range of air cooled water
chillers, designed for siting in internal plantrooms,
has been extended with nominal cooling
capacities from 46kW up to 264kW, previously
97kW. Aermec products are distributed
in the UK by AiAX.
The NRC features didw centrifugal fans which
enable the air to be ducted in and out of the
plantroom. It is available in cooling only, heat
pump and air cooled condensing versions. The
cooling only models have the option of partial or
total heat recovery capability.
The chillers all use environmentally friendly
R407C and deliver good efficiency using low
power consumption scroll compressors and high
efficiency plate type heat exchangers.
All models have any number of standard features
such as water strainers, evaporator heat
protection, and modular microprocessor control
system. As an option there are run and standby
pumps, storage tank and expansion tank modules.
Aermec is Europe’s largest manufacturer of
chillers producing in excess of 8,000 per year.

New TSI model 8375
AccuBalance® modular
air balancing tool
TSI announces the new TSI Model
8375 Modular Air
Balancing Tool.
This exceptionally
versatile testing
device for the HVAC
test and balance and
the industrial
hygiene professional
features a multi-purpose
digital manometer
that can be used
with a variety of common
test and balance
tools.
Available tools include a
capture hood, a relative
humidity and temperature
probe, an air flow probe,
a pitot probe, static
pressure probes, and a
velocity matrix. The
optional velocity matrix provides
fast readings of 16 measuring
points simultaneously, making it
ideal for a wide variety of measurements
in fume hoods,
Biological Safety Cabinets, and
HVAC systems.
Technicians will appreciate the
light weight (3.5 kg) and ergonomic
design of the AccuBalance capture
hood base
assembly,
especially
when making
over-the-head
measurements -
as well as the
fact it can be
powered by AC
mains or just 4 AA
rechargeable or
alkaline batteries.
The Model 8375’s
meter is easily
attached/detached
from the AccuBalance
base assembly to use
with various accessories
to perform a
wide variety of measurements:
air temperature,
relative
humidity, differential pressure,
static pressure, air velocity or volume,
and lab hood face velocities.
Data logging allows test data to be
downloaded to a PC using the
included TSI LogDat(tm) software
program.

Trade association calls
time on current attitudes
Sanyo launches the
highest efficiency
mini VRF
In its continuous effort to provide
the all round air conditioning
solution, SANYO - the Japanese
global air conditioning manufacturer
- has
announced the
launch of the latest
addition to its comprehensive
product
range: the ECOi MINI
range of small capacity
VRF systems.
Specifically developed
for the
European market,
this small, 2-pipe
heat pump VRF system
offers premium
quality air conditioning
for small to medium sized projects.
Bob Cowlard, General Manager UK
& Ireland, SANYO Air Conditioning
explains: “The ECOi Mini Range
will enable us to further grow and
strengthen our position in the UK
by entering the rapidly expanding
sector for small VRF systems which
now accounts for approximately
20% of the total VRF market. In line
with SANYO’s corporate policy of
The Heating and Ventilating Contractors
‘Association (HVCA) calls for a change in current
attitudes and a common approach to a
‘qualified industry’
Warning that the construction and building services
industries could undermine their recent
years of progress, the Heating and Ventilating
Contractors’ Association (HVCA) has called for a
complete review of the multitude of workforce
registrations schemes along with changes in attitudes
to quality.
At recent industry meetings Robert Higgs,
Director of HVCA, has taken the opportunity to
talk about the fundamental issue of a ‘qualified
workforce’. Higgs has said, “We must accept
that the plethora of standalone registration
schemes had created confusion throughout the
construction industry and among its clients. We
need to rationalise these schemes and it is vital
that we get this right.
“Organisations like the HVCA have a duty to,
and a vested interest in, making sure that
clients are able to differentiate between qualified
and unqualified finns.
“We accept that we must provide a workforce
that is competent and able to provide independent
verification of its credentials. This is why
we have already called for a set of principles
common to all registration schemes to be drawn
up and agreed, allowing qualified firms to register
only once.
“We also want clients to recognise the importance
and value of schemes that independently
verify the technical competence and commercial
capability of contractors and the skills of
their workforce - schemes like the HVCA’s own
independent member inspection and assessment.
“There will be little point in the industry spending
time and resources putting its house in order
if clients are going to continue specifying on
lowest price. It is vital therefore that we have
active client support, otherwise there is a danger
of the industry slipping back into its bad
habits and adversarial ways”.
The HVCA has also called for the Government to
take a lead on these issues. It points out that as
a major construction client it needed to clear up
the uncertainty caused by different departments
adopting different approaches to the
establishment of contractor competence.

only producing products that support
sustainability, the range offers
the highest efficiency ratings on
the market -and they are also the
quietest!”
“The 3 models within
the range, which provide
between 11 and
15.5kW of cooling
capacity, offer an
incredibly flexible
solution, as up to a
class-leading 10 indoor
units can be connected
to one, single phase
condensing unit. With
an indoor diversity
ratio of 130% and a
maximum pipe separation
of 150m, this means
just one 6HP ECOi Mini could condition,
for example, 10 hotel bedrooms
with a 2kW load”.
The ECOi Mini range features the
latest DC inverter technology
which, combined with R410A
refrigerant, provide EEL Category A
efficiency, with the 4HP model
offering a market-leading COP of
4.06 in cooling and 4.34 in heating.
