HydroAir & HydroJet
Accurate and hygienic liquid feeding systems
for piglet rearing

HydroAir & HydroJet – liquid feeding systems for piglet rearing for high demands
HydroAir and HydroJet were developed for piglets in
the rearing phase with weights from 6 to 40 kg. Both
systems can also be used for sow feeding. HydroJet
is especially well suited for small units with up to
1000 piglets, whereas HydroAir is best used on farms
with 1000 piglets and more.
Both systems can be used for preparation of feed
mixes from up to 40 different components thus providing
flexibility in the use of low-cost ingredients.
The feed can be prepared per valve (HydroJet) or, if
the same feed mix is used simultaneously for several
valves (HydroAir), which saves a lot of time.
Thanks to their compact design, HydroAir and Hydro-
Jet may be installed in very small feed kitchens
which is another advantage compared to traditional
liquid feeding systems.
What makes these two systems so different?
HydroAir-Synchron – this double-tank system allows a wide choice
of different recipes to be immediately available for supply of large
stocks
Sensor feeding systems are becoming more and
more important in piglet rearing. Such systems
make it possible to supply small and fresh feed por -
tions several times a day thus minimizing the risk of
infection and diarrhoea. Furthermore they help to
reduce a possible decline in daily weight gain after
weaning (keyword: weaning problems).
As HydroAir and HydroJet allow for preparation and
distribution of very small feed quantities, they are
ideally suited for repeated supply of fresh feed several
times per day. Of great importance is the ability
accurately to adjust the feed mix to the piglet’s nutrient
requirements and to supply a warm feed soup as
well as providing a gradual change of the feed mix
(phase feeding).
As every rearing expert knows, feed consumption,
especially in the first couple of days, is much higher
if the liquid feed is supplied warm. HydroAir and
HydroJet allow the temperature of the feed to be
adapted to the age of the piglets by means of feed
curves.
Since the feed is transported to the trough by means
of compressed air, all of it is eaten by the piglets. The
feed pipes are left completely empty after feeding
thus there are no residues.
HydroAir and HydroJet with sensor trough
and the correct animal : feeding place ratio
On-farm experience has shown that piglets should
be fed at a sensor-controlled trough. This way, fresh
feed is always available as required (appetite-controlled).
Every piglet should have approximately 8 cm
of feeding space. This corresponds to an animal :
feeding place ratio of 1 : 1 at the beginning of the
rearing period and a ratio of 2 : 1 at the end of the
rearing period. Such conditions make for uniform
feed consumption in the group with individual
weight gains of 450 g and more.

HydroAir – flexible and powerful
HydroJet – for small stocks
The main components of HydroAir include:
) mixing tank with agitator and tank cleaning;
) electronic weighing with 100 g scale resolution;
) positive displacement pump with a pump
capacity of 3600 l/h and a supply pressure of
up to 8 bar;
) feed valves;
) pipelines with a diameter of 25 or 32 mm;
) compressor with 4 or 7.5 kW motor, max.
pressure 10 bar.
Feed is prepared in a weighed mixing tank made of
stainless steel, available in different sizes (250, 500,
750 l). One HydroAir can supply up to 4500 piglets.
The main components of HydroJet include:
) compact high-pressure mixing tank made of
stainless steel (95 litres);
) electronic weighing with 10 g scale resolution;
) feed valves;
) pipelines with a diameter of 25 mm;
) compressor.
HydroJet allows the preparation and delivery of very
small quantities – approx. 2 kg – per valve. The
system operates with compressed air that means
no feed pump is required.
HydroJet is delivered pre-assembled and fits into
even the smallest feed kitchen.
One HydroJet can supply up to 1000 piglets.
The feed valves that are used consist of a T-ball valve
and a control unit. They operate electro-pneumatically
and need an air pressure of at least 6 bar.
Both systems are controlled
by an MC 99 NT
feeding computer. The
feeding computer is
capable of highly demanding
taks such as monitoring,
feeding protocols
and thorough evaluation
throughout the entire
growing period.

Advantages of compressed air technology
In contrast to many other liquid feeding systems,
HydroAir and HydroJet operate by means of compressed
air. That means:
) residue-free delivery of feed;
) no feed remains in the feed lines;
) vitamins and minerals can be fed without problems
(as they will not be left adhering to the inside of
the pipes after feeding is finished);
) phase feeding is possible;
) ensures ideal hygienic conditions and thus healthy
piglets;
) installation of the valves outside of the compartments,
therefore no electrical equipment in the
compartments.
Hygiene – HydroAir and HydroJet set high standards
Optimum hygienic conditions are a basic requirement
for high feed intake and feed conversion. The feed is
transported to the trough by means of compressed air.
Our well-proven acid fogger distributes
very small quantities of disinfectant
solution to the tank several times a day.
This way, the creation of a contaminant
film which would otherwise occur after
longer times of use is avoided. The fog
penetrates every corner of the mixing
tank, thus ensuring optimum disinfection
and hygiene.
In addition, the feed pipes can be rinsed
thoroughly with acidfied cleaning water.
The entire system is controlled by an
MC 99 NT feeding computer.
It is then dispensed without any residues. This means
that the feed lines will be completely emptied, there -
fore providing excellent hygienic conditions.
