TVD automatic filter

Recently we have improved a large soft fruit grower secondary filtration, by using 11 TVD automatic disc filters by Tavlit. HAving the units on-site will reduce water wastage by low flushing flow required by these units.

And make sure that in field irrigation is safe from any biofilm or build-up of algae from the main pipes.

Please get in touch if you require further technical info or advice .

Description of product:

TAVLIT line of automatic disc filters model TVD combines high-quality depth filtration with efficient flushing of the disc element. This unique automatic disc filter (patented), enables flushing at a very low pressure of 1.5 bar as compared to 3 bars normally required by such systems. The innovative technology of the filter uses venturi devices inserted at the spine´s inlets that introduce air during the flushing process to enhance it. the mixture of air and water enables more efficient flushing, uses smaller quantities of water for flushing, and shortens the flushing time. It also enables proper flushing at low pressure. The use of air also cushions the discs thereby reducing friction and prolonging the disc element life. The venturi devices insert air from the atmosphere and no external power or compressed air is required. The venturi devices are open only during flushing and do not operate during filtration. The filter element is composed of highly accurate grooved discs from excellent quality plastic materials. The grooved discs are compressed together to form the filtration element. The intersections between the grooves and the outer surface of the element offer large effective filtration surface with in depth area used to stop debris is especially effective in filtration of organic matter.

Fewer mixers, better results at the nursery DanRoses

When DanRoses took ownership of an older nursery on the Danish island Funen four years ago, seven fertilizer mixers from the 1980’s controlled all watering in the production, but the process was always monitored by the grower due to instability and errors. Now, fewer new mixers give better results – and peace of mind.

Since the 1980’s, seven AMI 900s and AMI 90s watered the 25,000 m2 indoor rose production at the Danish nursery DanRoses. But in later years, the grower began overseeing every single watering during daytime manually – simply because he was unsure of the old mixers’ ability to perform and whether the valves would open as intended.

“Some mornings we discovered that the planned watering at night hadn’t even started and we knew that we would not be able to catch up with watering before having to pack roses in our packing department. As a result, we would take a loss,” says Lars Olsen, who is responsible for the daily management, production, and sales at DanRoses.

Now, the seven old mixers have been replaced with three new AMI Penta from Senmatic, and the system needs no human control. “We now know that irrigation is carried out as planned with the correct dosage of fertilizer. I drive to work in the mornings with far more peace of mind and we experience less loss in our production,” says Lars Olsen, production and sales manager.

Watering reduced from 12 hours to just 2,5 hours daily
The old mixers had active watering activities for 12 hours every single day. One pump could control only one watering valve at a time and it took 40 minutes to water per valve.

With the AMI Pentas, active watering activities have been reduced to just 2,5 hours daily, irrigating through three valves simultaneously – in just 20 minutes. “We used to spend hours upon hours on watering. The old pumps were instable, we had no security when it came to fertilizer dosage and had to control the process manually. That time is now free for other tasks – and we even save fertilizer, because of the high accuracy of dosage. It’s much more effective,” says Lars.

Even greater focus on precision and large capacity with AMI Penta
Senmatic’s AMI Penta is designed to set even greater focus on the plants’ need for precision fertilizing and accurate acidity in the irrigation water and at the right time.

AMI Penta can control up to 100 groups with individual start conditions. For each group, you can choose between 20 different recipes with information about EC, pH, and the fertilizer mix. Each group can control up to 30 valves, and these can be chosen freely between the 200 valves available today in the mixer. Up to 9 valves can irrigate at the same time which gives a maximal utilization of the capacity. Irrigation time and volume can be set individually for each valve.

Air & Vacuum Air Valve AV10


The AV-010 Air & Vacuum Valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during drainage , pump shut-off or at water column separation.


Agricultural and landscape irrigation laterals.


The air & vacuum valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during drainage, pump shut-off or at water column separation.

High velocity air will not blow the float shut. Water entry will lift the float which seals the valve.

The smooth discharge of air reduces pressure surges and other destructive phenomena.

At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.

The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused

by water column separation. Air entry is essential to efficiently drain the system.

As the system starts to fill, the valve functions according to the following stages:

  1. Entrapped air is released by the valve.
  2. Water enters the valve, lifting the float and sealing the valve.

When internal pressure falls below atmospheric pressure (negative pressure):

The float will immediately drop down, opening the air & vacuum orifice.

Air will enter the system.


Main Features

  • Working pressure range: 0.2 – 10 bar
  • Testing pressure: 16 bar
  • Working Temperature : 600 C
  • Maximum intermittent temperature : 900 C
  • The body is made of high strength composite materials, and all operating parts are made of specially selected corrosion-resistant materials.
  • Drip-tight sealing at low pressure.
  • All parts are UV protected.
  • Lightweight, small dimensions, simple and reliable structure.

Valve Selection

  • Available in 3/4” (20mm), 2” (50mm)

Senmatic VLT new product

Product information of 5th March 2021

This information only deals with pressure control in AMI Penta and VA Penta as it requires a long explanation. Therefore, it is the only product change you get informed about this time. More information about product changes will follow the coming weeks.

If you need any clarification, you are of course always welcome to contact us.

AMI Penta and VA Penta – Pressure control

Pressure control is a pump controlled by a B&R VLT frequency controller. The user can add up to 2 VLT controllers to the system. All the pressure control settings have been gathered in one place. Common pressure control
Pressure control enabled
No: Disabling pressure control.
Yes: Enabling pressure control. It is required to go to I/O setup and make a config by pressing the button “Make config” to load VLT frequency controller 1 into the system. Pressure pump mode
A: Only VLT 1 is enabled.
A + B: VLT 1 and 2 are enabled. This function is used to run with two pressure pumps in parallel where each pump is controlled with a VLT frequency controller. A “Make config” is required to load VLT controller 2 into the system. Pressure pump 1
Settings in this section affects only VLT 1 controller. Minimum speed
Minimum speed for pressure pump 1. The speed will always be converted to revolutions per minute (rpm) in code behind and be sent to VLT 1 analog output. The minimum speed is independent of the PI regulator which means that the pump always will maintain the minimum speed even if the PI-demand is below that minimum speed. The controller will switch to the PI-demand as soon as the actual speed demand gets over the minimum speed. Start delay
A time delay for starting pressure pump 1. Stop delay
A time delay for stopping pressure pump 1. Pressure pump 2
This section appears when the pressure pump mode is set to A + B. Settings in this section affects only VLT controller 2. Minimum speed
Minimum speed for pressure pump 2. Pressure pump 2 will only start if pump 1 gives a signal to pump 2 to start. This is dependent on the setpoint “Pump 1 speed for start pump 2”. Pump 1 speed for start pump 2
The speed of pressure pump 1 to start pressure pump 2. Start/stop delay
A time delay for starting and stopping pressure pump 2 Start hysteresis
Hysteresis for starting up the pump. Start condition
Time: the start of pressure pump 2 is only dependent on pump 1 speed for start pump 2 and the time delay.
Pressure: The start of pressure pump 2 is dependent on pump 1 speed for start pump 2, a time delay and a pressure input switch. Regulation
I time
Set the integral time for the pressure regulation. P Factor
Set the Proportional factor for the pressure regulation. [bar] Common readings
This reading section is common for both pressure pumps. Pressure
Reading the actual water pressure. Pressure demand
Reading the wanted pressure demand. P Contribution
This is the Contribution from the P regulator. [%] I Contribution
This is the Contribution from the I regulator. [%] Readings
Reading the status of pump 1 and 2 Speed demand
Reading the current pump 1 and 2 speed demand. Pressure fault
Fault reset
Manual fault reset of pump 1 and 2. This can be used if the fault could not be auto reset within the pump alarm delay in the alarm settings. The reset button will only reset the latched fault if the error disappeared physically from the VLT. Alarm status
Off: Indicates that no fault exists on the VLT
On: Indicates that a fault exists on the VLT
