INJECTION AERATORS
for aeration, circulation, destratification and oxygenation This injectors are one of the best and most advanced
aeration systems worldwide, and also suitable for large ponds. They work with an for
endurance run produced, maintenance free, adjustable, submerged (also seawater resistant),
motor in different power sizes (0.37-1.50 kw (0.5-2.0 HP) 230 or 380 V/50 Hz). The rotating
propeller (2850 r.p.m.) produces an adjustable current, through which air drawn from the
surface and formed into fine evenly distributed bubbles. The diffused air aerate from the
bottom up and the circulation created from the fine bubbles displaces the surrounding
water, thus breaking up stratified water areas. This constant surge forces the pond to
turn over, bringing cooler bottom water to the surface, where it picks up additional
oxygen from the atmosphere. Therefore the dissolved oxygen is always as high as possible.
Through the eutrophication process (of faces and feeds) there is usually oxygen deficit
at depth, therefore this system works to an adjustable depth and introduces the oxygen
where it is needed, not only on the surface. If submerged, pure oxygen instead of air can
be introduced with exact dosage. Long contact time of the fine bubbles in the water,
ensures also this system is very effective. Depending on power and depth, the air flow
rate is up to 40 m3/kw/h and the oxygen introduction up to 1 kg/kw/h. At an oxygen
content of 6 mg O2/l at beginning, one 1.0 HP unit in use with air, introduce over 0.32 kg
O2/h which is the oxygen demand for over 2600 kg (table sized 250 g) trout's at a water
temperature of 10 °C, for approx. 1000 kg at 20 °C or up to 3000 kg of other species. |
INJECTORS without
further energy consumption This
"ECO" injector is a new developed static aerator for the water inlet pipe (1
") in tanks, raceways and small ponds, that works hydraulically and has no moving
parts. It is designed to ensure cost-effective use of any viable water source. For
degassing, aeration, oxygenation and dosing with chemicals (thereby avoiding the slightest
wastage and maximizing efficiency). In enriching the water with air or pure oxygen,
this aerator can create good circulation with a lesser amount of water than is usually
supplied, with consequent energy savings. It works hydraulically (from 0.2 bar and 0.4
l/sec. on) exploiting the act the water passing through it at high speed (achieved by
means of suitable flow rates and pressures with the special 3 interchangeable nozzles (for
approx. 30, 50 or 100 liter/minute) and creates a great pressure drop and consequently a
tremendous suction capacity, without introducing additional energy. |
PROPELLER AERATORS with water conveyer
The following types are available as standard:
|
AERATOR PUMPS with fountain spray pattern This "Spray" aerator pump with 10-25 m cable is specially suitable for ponds and introduce a lot of oxygen into the water. If the self floating pump is connected with the spray nozzle it becomes an aerator with fountain spray pattern. If the supplied nozzle is changed to the supplied pipe adaptor it can be used as a floating pump for irrigation. The change of these two functions doesn't need any tool. They have a very reasonable price and are easy to install, either floating on the water surface or submerged to depth (with an anchor stone).
The following types are available:
|
PADDLEWHEEL AERATORS for intensive production
|
PADDLEWHEEL SYSTEMS for effective oxygen introduction Aeration and/or oxygenation
is specially of economic importance in intensive farms. At this completely new developed
systems all possible failures and defects of other known products have been removed. The
systems have been tested under hardest conditions and have a very high
efficiency, with
the same time low investment and operation costs. There are no bearings of the wheel
(100-130 r.p.m) necessary and also no couplings and discs, this reduce friction lost and
increase the efficiency and also reduce the possible parts which could become
defect with
time. A very long self live and high efficiency is also guaranteed through the
worm-gearing. The motor is specially sealed against moisture. Paddles, wheel and frame are
made of stainless steel, the T-formed floats from thick UV- and ozone resistant material. |
RUBBER DIFFUSER with stainless steel frame
The following sizes are available as standard:
|
CERAMIC PLATE DIFFUSERS for micro bubbles
The two larger diffusers consist of 2 smaller plates! |
The fine
pored ceramic
tubes allow to diffuse the air in fine bubbles. The diffusers should be installed in the
same depth, but as deep as possible below the water surface. The floating cross diffuser
is placed on the water surface in the center of the tank or pond and fixed with a rope to
the shore so that it can move a little and aerate a larger area. |
GAS DIFFUSERS with high performance
|
MEMBRANE COMPRESSORS
for Direct Current
The following sizes are available as standard:
|
SIDE-CHANNEL
BLOWERS for water aeration or delivery
The following blowers are available:
The typical emerged blowers (type V) are installed only on the land, but at
almost any location. An advantage in recirculation systems is that the heat
in the air of a room can be used to heat the water. |
REGENERATIVE BLOWERS
for pressure or vacuum generation
Types with the following performance data* are available as standard:
*Performance data at pressure operation 50 Hz (= 2900 RPM), for air at 20 °C, pressure 1013 mbar, tolerance +/- 10 %. |
OXYGEN GENERATOR
SYSTEMS for intensive aquaculture
The following models are available as standard:
The stated
flows in m3/hour are for operation with reference to 15°C, 981 mbar, inlet pressure 7
bar, flow variance ±5%, oxygen purity 90 %, purity variance ±1%. |
