QUALITY water contamination

IMPORTANT?
Venting and degassing systems are essential
components of a modern installation.

Only thorough pre-venting before startup

and smoothly working operational degassing
guarantee stable working conditions. This
holds particularly true for long-span branched
systems with horizontal heating pipes and
cooling ceilings.

Appropriate system components must be

carefully selected based on the operation
principles and performance characteristics of
air vents, separators and degassing units.

Balancing valves and standard control valves

ENERGY EFFICIENCY

• Stable and precise temperature control in all operating conditions is guaranteed, if control valves and differential pressure controllers
are properly matched
• In the version with modulating control, the high authority of the valves is ensured by the differential pressure controllers, which
stabilise the differential pressure
• Low energy consumption when pumping
• Reduction of heat loss in return pipes.

INVESTMENT

• Higher investment costs compared to E2 based on multi-purpose balancing and control valves
• High flow rates determine the large diameter of the Dp controllers (the use of TA-PILOT-R with its linear design reduces the diameter
and thus the investment costs)
• Extraordinary measurement and diagnostic capabilities of the IMI TA valves allow for complete system diagnostics without the need
for additional investments in other devices.
• High flexibility. Possibility of phased start-up or expansion without the need of rebalancing the already functioning part

SIZING

• Simple valve matching based on nominal flow and minimum pressure drop (1/3 of the total pressure drop in the stabilized cycle) for
the correct authority level
• Need to check the closing pressure of the actuators
• Quick matching with the use of software: HySelect, HyTools, Instal-therm, Auditor

COMMISSIONING

• Preset of the valves based on hydraulic calculations with the option of gentle correction on site
• The Dp controllers should be set according to the actual pressure drops on the branch
• Use precise IMI TA balancing methods to adjust flows while optimizing the pump’s operating point
• The extensive diagnostic capabilities of IMI TA valves in combination with TA-SCOPE make it easy to identify and resolve any
possible system failure.

• Variable speed pump control and Dp controllers for stable differential pressure conditions on thermostatic valves allow to obtain low
temperature deviations and quiet operation
• Low energy consumption when pumping
• Reduction of heat loss in return pipes
• Low return temperature increases the energy efficiency of heat pumps and condensing boilers

INVESTMENT

• Low investment costs and fast return on investment

• Highest quality and long service life
• The return shut-off valves and connection kits facilitate maintenance work through the shut-off and drain functions of the radiator.
• Balancing valves and Dp controllers with outstanding measurement and diagnostic capabilities help you set the optimum pump lift
height and identify possible system faults
• High flexibility. Possibility of phased start-up or expansion without the need of rebalancing the already functioning part

SIZING

• Matching of balancing valves and Dp controllers according to the differential pressure in the range of 1-2K, in relation to the minimum
recommended pressure drop

• IMI Heimeier’s extensive product portfolio offers optimum solutions for any type of radiator or floor heating.
• NOTES: The use of pressure-independent balancing and control valves (PIBCV) is prohibited in systems with thermostatic valves.
They only limit the maximum flow. At the same time, they increase the pump’s lifting height by allowing excess pressure to pass
through to the thermostatic valves during most of the heating season due to the fact that the flows are below the nominal values.
• Quick matching with the use of software: HySelect, HyTools, Instal-therm, Auditor

COMMISSIONING

• Preset of the valves based on hydraulic calculations with the option of gentle correction on site
• Direct measurement of the actual flow and available differential pressure helps to set the minimum required lifting height of the pump
and ensure quiet and efficient operation
• We recommend selecting the thermostatic heads depending on the room function and indicating the recommended temperature
settings alternatively, they may be locked at the thermostatic head type B.

Heating system – constant flow

Balancing and standard control valves

ENERGY EFFICIENCY

• High control stability due to constant pressure distribution

• Increased energy consumption when pumping due to constant flow throughout the heating season
• High heat loss on return pipes under partial load.
• A high return temperature at partial heat demand reduces the efficiency of condensing boilers, and in the nodes, it raises the return
water temperature on the network side.
• Dirty filters and overflow significantly increase annual operating costs

INVESTMENT

• Large number of valves installed.

• It is not possible to apply the coefficient of non-uniformity and reduce the size of pipes.
• Longer period of reimbursement of costs incurred for the purchase of electronic pumps and condensing boilers
• Constant operating mode reduces pump life.

SIZING

• A hydraulic calculation is required for 3-way control valves and balancing valves.
• Adequate Kvs value is essential for the high authority of a 3-way valve.
• 3-way valves regulating small end receivers need a reduced Kvs value in the bypass direction or an additional balancing valve to
restrict excess flow by bypassing partial load or when the valve is fully closed.
• Quick matching with the use of software: HySelect, HyTools, Instal-therm, Auditor

COMMISSIONING

• Preset of the valves based on hydraulic calculations with optional correction according to measurement on the object
• Preset of the pump’s lifting height to achieve a constant nominal flow, a constant speed is necessary.
• During start-up, it is important to check the compatibility of the flow between primary and secondary flow in the air handling unit.
The primary flow should be 5% higher if the nominal flow temperatures are identical.

SOURCE

Primary and secondary pumps work in series

The self-regulating variable flow separation system is ideal for variable primary and secondary circuits where a secondary pump has to be
used due to a lack of sufficient availability from the primary pump. Example: Compact heat node with integrated supply pump for the main
distributor in the circulation pumps. The feed water temperature of individual circuits is maintained as supplied from the source. The nominal
bypass flow is usually 10% of the total secondary flow, so the bypass balancing valve is small in size. The minimum flow through bypasses
can also be determined by the minimum flow through the primary pump.

Four-pipe heating and cooling

system – Variable flow
ENERGY EFFICIENCY

• Stable and precise temperature control in all operating conditions

• Precise volume flow for heating and cooling.
• Motorized drive with very low power consumption in standby mode.
• Pressure independent control with high authority for continuous control.
• Low energy consumption of the pump (no excessive flow).
• The very low pressure drop in the IMI TA valves reduces the required pump availability pressure.
• Lowest possible return temperatures for minimum heat loss in return lines.

INVESTMENT

• A solution with as few valves as possible.

• Possibility of using cheaper actuators (lower closing pressure required).
• IMI TA valves have unique measurement and diagnostic functions for full system diagnostics at no additional cost
• Quick return on investment (highest quality, extraordinary service life, large energy savings)
• Additional devices for stabilizing the differential pressure are not necessary.
• Economical 6-way valve without special Kvs inserts in the sockets.
• High flexibility. The heating system can be built or extended in stages without having to repeat the hydraulic balancing process.
Simply adjust the pump settings to your new system requirements.

SIZING

• Simple matching of a valve based on nominal flow.

• Simple 6-way valve selection without the need to calculate the Kvs value, as it is only used as a switching valve.
• It is not necessary to verify the authority of the control valve.
• Easy matching of the correct actuator
• HySelect for hydraulic calculations can also be applied.

STAR-UP

• Simple setting of the maximum flow rate on each valve.

• Flows and all parameters are set directly with the use of HyTune.
• Menu settings that are displayed graphically in HyTune.
• Parameter settings of other identical drives can be easily copied.
• The flow and available differential pressure can be directly measured, helping to optimise pump operation.
• TA-SCOPE utilizes the outstanding diagnostic capabilities of IMI TA valves to detect and correct all potential faults.
