The following questions can be answered based on
actual weather data:
With regenerative heat recovery, is re-humidification
through condensation adequate, or should a hygro-
scopic coating be used?
Should a humidifier be additionally provided?
How much heat/cooling power is enough?
Can dehumidification (e.g. in areas surrounding
swimming pools) be carried out without using a
mechanical refrigeration system?

Standards and regulations - export HANSA worldwide CE-marking (European Union, Switzerland and Turkey) As a member of the Manufacturers Association of RLT, we concur with the view that our machinery used in ventilation and air conditioning equipment must be in line with the EG Machinery Directive. As a consequence, our customers in the European Union, Switzerland and Turkey enjoy an immediate and decided advantage: Each complete unit is exten- sively tested according to the machinery, low vol- tage and EMC guidelines, and are appropriately CE labelled. This label assures the operator and the plan- ner/equipment manufacturer of legal certainty. A complete machine that is capable of CE marking comprises certain mandatory safety equipment (e.g. dedicated repair switch), the wiring and the control panel, with a controller, if necessary. While it is easy for a foreign company to add these components, the operator loses the advantage of having the CE decla- ration and must pay to have the appropriate certifica- tion carried out at his own expense. In addition, HANSA's control-technical processing si- gnificantly facilitates adapting the unit to match the customer's requests. Interfaces are avoided and the owner benefits from the experience of our engineers by using systems that are efficient and are able to meet demand. UL-marking (USA and Canada) Of course, as a UL-certified company, we manufac- ture control panels that meet UL standards for our customers in the U.S. and Canada, and we label them accordingly. GOST-R/TR certification (the Russian Federation, etc.) Our distributor for Eastern Europe, excluding the Eu- ropean Union countries, certify our equipment accor- ding to GOST-R/TR guidelines for the safe machinery design. 8
During many years of collaboration, numerous pro-
jects have been implemented on the campus of
Hamilton College in Clinton, New York (below),
including the award-winning LEED expansion and
modernization of the Kirner-Johnson Building (left),
the Sounders Center or the Wellin Museum of Art
(pictured below left), which requires a level of very
precise air conditioning to maintain the value of the

Standards and regulations - certificates
Certified quality
The application-specific standards in design and ma-
nufacturing must be especially taken into account, in
addition to the European directives (e.g. MD, EMC,
LVD, ATEX) and the general principles for the design
and construction of air handling units.
For more than 45 years, we have been building air
handling units for supply of spaces occupied by peo-
ple, including hospitals, swimming pools, server are-
as, kitchens and food outlets.
In addition to our own independent, standards-com-
pliant design and manufacturing processes, we regu-
larly have independent laboratories check our units to
ensure compliance with all relevant standards.

Profiles
Depending on the size of the unit and customer re-
quirements, we use 30 or 50 mm frame profiles (an-
odized, if necessary) made of aluminum (R30 and
R50 profiles).
These profiles are also used thermally separated and
insulated per cube type as needed (R30I and R50I).
These profiles are characterized by a good thermal
insulation and the avoidance of thermal bridges. This R30 profile R30I profile
avoids wasting energy and condensation problems.
Double-lip EPDM rubber seals are inserted into all the
profiles, which are characterized by
resistance to aging

Panels
Double-skin panels are made from zinc-plated sheet
steel with optional coating. The folding technique
and assembly used prevent cutting edges.
R50-panels can be carried out thermally separated
and be foamed up or filled with mineral wool.
Besides fixed, mounted elements, removable doors
and hinged doors are installed, which are closed us-
ing clamps or a catch.
A variety of security measures provide security in
hazardous areas:

Control technology
Our technical control department has decades of ex-
perience in HVAC systems control. We rely on dif-
ferent systems to optimally meet each customer's
needs and requirements.
The control strategies are derived from the installed
components and their interconnection (defined in the
control scheme), the requirements (e.g. for operating
the swimming pool, the hospital, kitchen, etc.) and
operational conditions (e.g., the geographical loca-
tion). Optimally, a detailed clarification occurs as ear-
ly as the bidding phase. If this is not possible, an ap-
propriate margin must be provided in order to adapt
to parameters and algorithms after commissioning. Control cabinet with Saia-DDC
Hand-held devices, LCD panels, web panels or the
connecting standard PCs via the Ethernet (LAN and
Internet) provide access to the technology, whose
possibilities are defined precisely by the user's func-
tions. In this regard, we implement different user le-
vels, each of which are secured by passwords.
We highly recommend remote access by connec-
ting to the Internet or, if that is not possible, to a
GSM modem. Doing this enables our team to cost-
effectively carry out remote maintenance at the main HVAC 1 : 1.8 : 07.16

Version 05 / 2019 – Subject to construction modificationsComponents - fans
Designs
The choice of a suitable design depends first on the
operating conditions. The following must be taken
into consideration:
the air flow
the required pressure
the available space
Fans with open impellers utilizing backward curved
blades are mainly used today. They are characte-
rized by high efficiency and the fact that they gene-
rate high pressure. They can also be placed on the
suction or pressure side of the components that are
used, because they have a lower dynamic pressure in
the outlet area. Taken together, this allows a flexible
design whose air-handling units are energy-efficient
and quiet.
Motors
Today, direct drive fan wheels have largely replace

motors and reducing the pollution in the unit through EC fan module (EBM-Papst) in standard version
abrasion. The speed control is typically done using with spider suspension (vibration-isolated mounting
a variable frequency drive converter for three-phase on the pressure bulkhead)
motors or by using a control signal for BLDC motors
(EC motors). In both cases, the speed can be cont-
rolled as required by the DDC.
BLDC motors are used to provide power up to about
11 kW (37,533 BTU/h). The benefits are manifested
in the increased efficiency and using the outer rotor
is uncomplicated.
Models
Certifications
In general, fans do not take over safety functions
unless they are explicitly designed and certified to
do so.
Typically, the maximum allowable temperature
of the delivered air is 40 °C (104 °F). Special
designs allow higher temperatures and are thus Retractable fan module (Ziehl-Abegg) in a coated version

Speed-controlled
Compressors
Speed-controlled compressors offer the most advan-
ced solution to continuously adapt the cooling capa-
city to varying requirements.
Significant energy-savings at the highest efficiency
can be realized by stepless controlled operation. An
expensive stop-and-go operation can be avoided in
favor of the unit's lifespan.
For many years, a number of buildings on the Harvard University campus in Cambridge, Massachusetts have used HANSA
ventilation and air-conditioning equipment.
22Heat Pumps for
Pool Dehumidification
In the field of swimming pool dehumidification, the
heat pump is an effective system for dehumidify-
ing and reheating. Our HKG-PL-P / PWT / PT / DPT de-
vices are specifically designed for this purpose, and
also provide a circulation system that retains 100%
of the used energy, in addition to its long service life
due to increased corrosion protection.
In addition, pool water condensers can be used to
heat the water. It is the same case here as with the
integrated chilled water production: our customers
