1. Identification
This chapter contains general information about the Enmix. The purpose of this chapter is to
indicate the limits and overall operation of the Enmix, and the areas in which it is used.
1.1 General
The low-speed Enmix Basic is the ideal solution for mixing liquids and keeping them in motion in
fertiliser tanks or tanks for other mixed liquids. The Enmix can also be used for mixing solid
fertilisers, for example from big bags. In modern greenhouse horticulture, the ever-increasing size
of mixing tanks can create problems when solid fertilisers need to be properly dissolved in the
water. The Enmix agitator mixer is the most optimal solution for this.
1.1.1 Description of the system/machine
The Enmix consists of a frame, a motor with reduction gearbox and a shaft with mixer blade
made of 304 stainless steel. The frame and mixer are available in various types –short/long
frame, short/long mixer shaft and 50/60Hz –and they can be adjusted to fit the dimensions of
the liquid tank, up to a maximum width of 246cm and depth of 150cm. The mixer blade has a
turn diameter of 75/100cm, rotating slowly and ensuring that all the contents of the tank, up to a
maximum volume of 10m³, are kept sufficiently in motion. The Enmix Basic is delivered as a
flatpack and can be assembled, mounted and installed on-site by the installer.

2. Description
This chapter describes how the Enmix should be used and the applications for which it is suitable.
The general description and outline of the working principle offer an understanding of the
intended purpose of this machine.
2.1 General
The purpose of the Enmix Basic is the compact and efficient supply of a complete agitator mixer.
There are two different models of the Enmix Basic, which are suitable for liquid tanks with a width
of 1100 to 2500mm and a depth of 180 to 1500mm, up to a maximum volume of 10m³.
The Enmix is suitable for mixing liquids containing fibres up to a maximum length of 5mm, with a
viscosity of <1000mPas and a minimum pH of 4.
The Enmix is delivered as a flatpack and must be assembled on-site by the installer. All the
necessary materials are supplied, including tools and gloves. However, the attachment materials
for mounting the Enmix on the mixing tank are not included. Chapter 4 of this manual gives a
step-by-step description of how to assemble the Enmix.
Annex 3 shows which Enmix model must be used for the correct dimensions of the liquid tank.
2.2 Working principle
The Enmix is designed for mixing liquids and/or keeping them in motion in fertiliser tanks or tanks
for other liquids. The Enmix can also be used for solid fertilisers, for example from big bags.
The mixer blade rotates slowly (94 rpm in the 50Hz variant, 112 rpm in the 60Hz variant), which
ensures that no foaming occurs in the liquid tank. If the Enmix will be used in a round tank, we
advise that two vertical strips are fitted inside the tank, to prevent a vortex or swirling motion of
the entire contents. These strips serve as anti-vortex baffles around the shaft and ensure correct
mixing within the tank.
2.3 Transport and storage
The Enmix is delivered in several packages; see section 1.1.4 for a detailed explanation. Both the
transport and storage require a clean, dry environment with a minimum ambient temperature of
0˚C. All the packages must be handled with great care, especially the package containing the
mixer shaft, since damage to the mixer shaft can have serious adverse consequences for the
entire Enmix agitator mixer.

3. Safety instructions
The installer must ensure at all times that the Enmix is correctly assembled and installed; in case
of doubt, the manufacturer or supplier must be contacted.
During maintenance on the Enmix, the power supply cable of the motor with reduction gearbox
must be interrupted and made safe. This will prevent electrocution and will ensure that the Enmix
does not suddenly start to operate.
If activities in the form of mechanical or electrical modifications are planned, it is essential to
inform the manufacturer or supplier in advance, so that possible hazards can be prevented.
The following safety instructions are applicable to the Enmix Basic.

4. Assembly and installation
This chapter describes how the Enmix must be assembled and installed. You must read the entire
manual carefully before starting on the assembly and installation. We recommend that the
assembly and installation are carried out by two people.
4.1 General
The Enmix agitator mixer and mounting frame are made entirely of stainless steel and are
delivered as a flatpack, in accordance with the dimensions of the liquid tank. The mixer blade has
a turn diameter of 100cm (or 75cm in the 60Hz variant); it rotates slowly and ensures that all the
contents of the tank, up to a maximum volume of 10m³, are kept sufficiently in motion.
The Enmix is delivered in three packages: the electric motor with reduction gearbox, the frame
and the mixer shaft. For tanks with a depth >100cm, there is also an additional package: a shaft
guide, which is easy to fasten to the frame and gives extra support for the mixer shaft.
PLEASE NOTE: The Enmix mixer blade must be screened in some way to ensure that users do
not come into contact with it; for this, you should use a cover and grille or other adequate
protective device.
4.2 Installation instructions
After the Enmix has been fully assembled, it can be installed on the liquid tank. You are strongly
advised to take the following points into account during the installation:
•The Enmix frame must be attached to the liquid tank with four m8 bolts, locknuts and
washers (not supplied).
•The cooling fan cover of the electric motor must not be impeded by any obstacles; the
motor must be able to intake enough air.
•The electric motor must be connected to the electricity network in conformity with
NEN-1010.
•The electric motor must be earthed at all times, to prevent electrocution.
4.3 Delivery checklist
Before starting to assemble the Enmix, make sure that all parts are present. Annex 1 provides an
overview of the parts that the various packages contain.
4.4 Assembly
This section gives a step-by-step description of how to assemble the Enmix. Follow all these steps
carefully, to prevent problems later.
PLEASE NOTE: When attaching all the separate bolts, you should lubricate them in advance with
the supplied bolt grease; a small quantity at the end of the thread is sufficient. This will ensure
that the stainless steel does not become ‘galled’ and can no longer be removed.
To prevent possible hand injury, one pair of gloves is supplied; these are in the package
containing the frame (A).
4.4.1 Measuring the liquid tank
1. Measure the width and depth of the liquid tank;
2. In Annex 3, fill in the centre-to-centre distance and tank depth;
3. Check that you have the correct frame and mixer shaft (short/long).
