1 Introduction
Ridder Growing Solutions supplies both high-tech and simple solutions for large- and
small-scale horticulture companies. Ridder Growing Solutions‘s range is divided into
three product categories:
Water Treatment
Process Automation
Management Systems
The Ridder HortiJet is part of our range of water treatment products and is available
in two models:
HortiJet Pro;
HortiJet-Go!
The difference between these models is in how they are controlled. The HortiJet Pro
offers more advanced options.
This is the installation and user manual for the HortiJet Pro. This manual was
originally published in Dutch.
1.1 Introduction
The HortiJet Pro mixes the water with the fertilizers using a bypass from the main
irrigation pipe; this process is automated. This is also known as a 'bypass fertigation
system'.
The features of this system include:
Proven technology for soil-based crops
Compact and economical solution for large-scale irrigation
Robust, vertical pump for an extensive pressure range
Mixing chamber for improved mixing of water and fertilizers
Dosing channels that can handle up to 1000 L/h
Flexible and intuitive controls
One controller for both fertigation and climate
Remote control option
For hydroponics (cultivation on substrate), we recommend the Ridder FertiMiX.
1.2 Aims
This manual has two aims:
1. The manual describes how to install and connect the HortiJet Pro.
2. This manual describes the functioning of the HortiJet Pro and how to maintain it.

2.2 Process description
The HortiJet works as follows:
Fresh water is supplied.
On the main pipe, there is:
an main irrigation pump which supplies water,
a filter for the filtration of the water,
a pressure gauge (both before and after the filter),
a PSV to maintain the pressure at a constant level.
The filter and pressure gauges can also be fitted to the main pipe
between the inlet and the outlet (nos. 6 & 7 in Figure 2-1). This is for
extra mixing of the water and fertilizers.
The following processes can also be carried out on the main pipe:
(optional) pre-blending of different types of water supply based on an EC
measurement,
(optional) flow meter on the main pipe.
To ensure that the water can flow optimally through the HortiJet Pro, a branch
(with manual valve) is created from the main pipe.
Some of the water from the main pipe flows into the HortiJet Pro via the inlet.
The pressure in the inlet is reduced by a PRV.
After the PRV, there are EC and pH sensors (optional). The dosage of fertilizers
and acid can be adjusted based on the incoming data from these sensors.
The pressure switch monitors whether the pressure of the water supply is
sufficient.
The fertilizers are supplied to the HortiJet from fertilizer tanks, via supply
hoses.
There are five venturis in the HortiJet. The fertilizers are drawn through these.
There are dosing channels connected to the venturis (maximum of four for
fertilizers, maximum of one for acid). This is where the fertilizers are added.
The supply hoses are connected to the dosing channels.
From the distribution pipe, the water flows through the venturis to the collection
pipe. There is a compensation channel parallel to the venturis. The amount of
water flowing through the compensation channel will depend on the number of
dosing channels connected. There is a PRV in the compensation channel. This is
used to set the pressure difference across the venturis.
The process then goes through the air release valve and the HortiJet pump. The
HortiJet pump sends the water into the mixing chamber where the fertilizers
and water mix.
The water then flows past the PSV to set the pressure at which the water is
pushed back into the main pipe via the outlet. The PRVs and the PSV enable both
the pressure and the flow in the HortiJet to be regulated.
The water that leaves the HortiJet mixes with the water in the main pipe.
Most of the water goes to the irrigation valves and the crop. Some of the water
circulates back to the HortiJet so that the EC and pH levels of the irrigation
water can be measured.
HortiJet Pro
10

The entire process is regulated by the HortiMaX CX500 process controller. Its tasks
include:
ensuring that the correct fertigation recipe is mixed (proportion of fertilizers
and water).
controlling the valves to ensure that the water reaches the crop.
2.3 Product specifications
The HortiJet Pro is available in various configurations, because different dosing
channels, pumps, sensors and I/O modules can be added to the HortiJet Pro. This is
described in the following sections.

* You can calculate the required fertilizer dosing capacity by multiplying the
maximum required irrigation water (main pipe capacity) by the maximum required
fertilizer dosing ratio.
EXAMPLE
With a dosing ratio of up to 10L per fertilizer per m3of irrigation water, the
1000 L/h dosing channels are suitable for irrigation of between 60 and 100
m3/h.
** Acid can also be dosed using a fertilizer dosing channel; the indicated acid
resistance should be taken into account.
*** One HortiJet has between one and four fertilizer dosing channels and, optionally,
one acid dosing channel.
2.3.3 Pumps
The pump type depends on the dosing capacity, the pressure in the main pipe and the
electrical frequency.
2.3.4 Sensors

Depending on the configuration, the following sensors can be added:
EC sensor: the EC sensor measures the concentration of fertilizers in the water.
pH sensor: the pH sensor measures the acidity level of the water.
You can have zero, one or two sensors of both types. The HortiJet Pro is supplied
without sensors as standard.
If there is one EC / pH sensor: this is the control sensor.
If two EC / pH sensors are present: the verification sensor checks the
functioning of the control sensor.
On the HortiJet Pro, the positions of the sensors for the HortiJet-Go! are capped.
Please consult the supplied OEM manuals for the correct use and maintenance of the
relevant components.
2.3.5 I/O modules
Peripherals (inputs and outputs) can be connected to an I/O module. The HortiJet Pro
uses I/O modules from the CompactiMa series; these I/O modules are also called
CompactiMa modules. You mount the modules in a cabinet by simply clicking them
into place. Wires fitted with ferrules can be inserted into a module without any tools.
The table below provides an overview of the various types of CompactiMa modules in
the HortiJet Pro:
Module type When relevant
DO16-AI16 Always
EC2-pH2 If the EC, pH and/or flow are measured.
Other types of CompactiMa modules are not part of the HortiJet itself, but can be
supplied as accessories.

For more information, please consult the "CompactiMa Modules Insert".
2.4 Control
The HortiJet Pro is controlled by a HortiMaX CX500 process controller. The HortiMaX
CX500 software runs on the IPC that is located inside the main panel of the hardware
cabinet.
The HortiMaX CX500 has a supporting tool called: CX Assistant. The dealer can
configure the HortiMaX CX500 using this.
The HortiMaX CX500 can be operated using Synopta. Using Synopta, it is possible to
control the HortiMaX CX500 remotely, in an advanced and convenient manner.
The HortiMaX CX500 and Synopta are not part of the HortiJet Pro, but are
available separately.
2.4.1 HortiMaX CX500
The HortiMaX CX500 not only optimizes the climate inside the greenhouse, but also
provides control over irrigation, buffer tanks and energy. The HortiMaX CX500 is the
ultimate automation solution, is suitable for every greenhouse and every crop, and
can expand as the grower's business expands.
For more information on the HortiMaX CX500, see the “Dealer guide to the
HortiMaX CX500” or "CX500 Brochure".
2.4.2 CX Assistant
The CX Assistant is the configuration, calculation, installation and management tool
for the HortiMaX CX500. The tool has been designed especially for dealers. The tool
provides support for most of the tasks that you need to perform with the HortiMaX
CX500. You can also use it as a marketing tool during the quotation process.
With the CX Assistant, you can:
define a configuration,
check a configuration,
generate a wiring list,
see which I/O modules and other components are required,
request a licence,
install and activate a configuration in the HortiMaX CX500,
download and modify an existing configuration,
analyse the impact on costs of the chosen software configuration.
For more information on the CX Assistant, see the “CX Assistant tutorial”
guide.
2.4.3 Synopta
This is the advanced all-in-one program that offers easy navigation and a range of
setting options to operate the HortiMaX CX500 easily.
