Basic Concepts for the Calculation of Expansion Automats

To select the right expansion automat it is necessary to understand the following principles:

• Static height This is the height of the system between the connection of the Flexcon expansion appliance and the highest point, measured in water column metres (1 wcm = 0.1 bar).

Sizing Expansion Automats• System water capacity

This is the total volume of water in the entire system including heat source, radiators, pipe work etc.

• Increase in water volume (in %) The table below shows the percentage volume increase of water as temperature increases from 10 °C to 110 °C.

• Expansion volume The expansion volume is determined in the following way: expansion volume = capacity x increase in volume at the average heating temperature.

Example: heating temperature 90/70 °C (average 80 °C) = 2.89%.

• Heating/Cooling power This is the sum of the nominal heating capacities.

• Capacity of the expansion automat The capacity of a pump expansion automat is determined in the following way: capacity of expansion appliance = 1.3 x expansion volume (in the case of the Flexcon M-K / C the factor is 1.4).

The factor of 1.3 is based on the following assumptions:• The expansion vessel has to hold at least 10%

more than the calculated expansion volume.• The volume of the vessel allows for refilling

and min./max. levels.• Corrections to tolerances which, according to

various standards, are admissible for parts of the system.

The Flexcon M-K/U compressor expansion automats store the expansion water from the system. They also hold the system pressure at the pre-set level within clearly defined limits. Water and compressed air are separated from each other by a removable high-quality butyl-rubber bladder which has a high diffusion density (low gas permeability).

Noticeable features of the Flexcon M-K/U are the high level of reliability and sturdiness. The Flexcon M-K/U is adaptable to a wide range of situations and there are plenty of optional accessories which mean that it can be put to many different uses in countless systems. They are low-noise compressors that require no oil.

The entirely micro-processor driven control unit in the Flexcon M-K/U expansion automat has a number of parameters that can be set to any variable within a given range.

The benefits of the Flexcon M-K/U• Stable system pressure and a large working vessel

volume.• With red epoxy-powder coating.• Easy to install and commission.• Intuitieve SPC controller. This is a 'plug and

play' control system including clear instructions via the sensor touch screen, intuitive and easy to use with economic energy-save mode.

FLAMCOMAT GB

The Flamcomat is a modern, pump-driven pressurisation unit. Thanks to its sophisticated construction we have made it possible to incorporate important functions into one compact unit.

The Flamcomat consists of a pump unit and a pressureless vessel. This modular expansion system can be expanded with additional vessels and accessories from our comprehensive range.

Connection assembly sensor (optional)The Flamcomat de-aeration process can be performed even more economically. When the pre-set minimum gas volume has been reached, the normal de-aeration process is stopped until the next time the sensor detects an excessive level of gas in the expansion fluid.

In this way we can tailor the equipment precisely to the needs of your system.

The Flamcomat is suitable for any size of heating installation and for both refrigeration and air-conditioning installations. The Flamcomat makes sure that the system pressure remains within precise limits and that the system is topped-up automatically should there be any requirements. The venting process is incorporated, dynamic and energy-efficient.

1. ColdThe automat contains a small amount of water. The automat is still at rest.

5. Topping-upIf the water level in the vessel drops to a critical level, an appropriate amount of water will be carefully pumped into the system from the water mains. This water will be de-aerated (by pressure loss and the PALL rings), before entering the vessel.

3. Full powerWhen the system has warmed up completely, the vessel will be almost full to capacity.

2. Warming upThe volume of water and the system pressure increases. The unit responds to this by opening the solenoid valve. Water flows into the pressureless vessel. The water in the vessel is de-aerated due to both the drop in pressure and the presence of the PALL rings.

4. Cooling downThe volume of water and the system pressure decreases. The de-aerated water is pumped from the pressureless vessel back into the system. This restores the system pressure.

How the Automat Works

1) Additional vessel(s) connection must have the same pipeline diameter and vessels must be configured symmetrically. 2) Use if return temperature > 70 °C.

The Flamcomat is a versatile expansion equipment with supreme technical performance. The de-aeration capacity is not dependent on the circulation speed or the pressure in the system. In systems with a large difference between summer and winter operation, we recommend using a double (load-dependant) pumpunit.

5. Topping-upIf the water level in the vessel drops to a critical level, an appropriate amount of water will be carefully pumped into the system from the water mains. This water will be de-aerated (by pressure loss and the PALL rings), before entering the vessel.

3. Full powerWhen the system has warmed up completely, the vessel will be almost full to capacity.

2. Warming upThe volume of water and the system pressure increases. The unit responds to this by opening the solenoid valve. Water flows into the pressureless vessel. The water in the vessel is de-aerated due to both the drop in pressure and the presence of the PALL rings.

4. Cooling downThe volume of water and the system pressure decreases. The de-aerated water is pumped from the pressureless vessel back into the system. This restores the system pressure.

How the Automat Works

1) Additional vessel(s) connection must have the same pipeline diameter and vessels must be configured symmetrically. 2) Use if return temperature > 70 °C.

The Flamcomat is a versatile expansion equipment with supreme technical performance. The de-aeration capacity is not dependent on the circulation speed or the pressure in the system. In systems with a large difference between summer and winter operation, we recommend using a double (load-dependant) pumpunit.


FLAMCOMAT - PUMP UNITS


Flamcomats with pump units are used for storage of expansion water, de-aeration and topping up your installation automatically as an integrated controlled unit carried out with state of the art micro-electronics.

• The easy to use, detachable control unit shows all system operation and fault conditions clearly and conveniently. The control unit can also be used remotely, up to a distance of 500 metres, so that you can view the system from your workstation and may be interfaced with external systems to give a networked control and alarm system.

•By using Flamco-patented PALL-rings, gas bubbles down to a size of 18 microns can be removed from the system. The PALL-rings have a large adhesive surface, which means that the Flamcomat can eliminate large and small air bubbles from your system. This is described further in the independent research report commissioned from the Technical University of Delft, the Netherlands, which can be obtained from Flamco.

•State-of-the-art technology gives low power usage, long life and ease of maintenance.•Red (RAL 3002) epoxy powder coating.•Maximum temperature on bladder (EN 13831/8): 70 °C.•Maximum temperature at (heating) outlet: 120 °C.

For large or tall sealed heated or chilled water systems traditional expansion vessels are not always the most effi cient solution in terms of operational pressure or physical footprint. Flamco expansion systems balance the system pressure, using a highly effi cient vessel design and control equipment.

We produce a comprehensive range of models that offer high-quality performance and versatility which may be further enhanced by the addition of numerous optional accessories. Flamco has an adaptable, modular range to suit every requirement.

Flamco-Fill PE Top-up Unit (pressurisation)

The Flamco-Fill PE pressurisation units monitor the pressure in sealed heating and cooling installations and tops them up as necessary. Topping-up depends on the pressure or level at a pre-set interval. There are two working methods available. One for installations with expansion automats (command based on level in automat) and one for installations with Flexcon expansion vessels (command based on installation pressure).

•All models have an impulse water meter for monitoring the amount of water topped up.•Any malfunctions will result in a visible alarm and may be made visible automatically in the

malfunction log, even via remote control (dead socket).
