In-Line Duct Fans MIXVENT-TD IN-LINE MIXED FLOW DUCT FANS MIXVENT-TD Fan Systems MIXVENT TD / MIXVENT TD-T MIXVENT TD x 2 ACCESSORIES The MIXVENT system has been designed to compliment the MIXVENT-TD range of in-line fans. All MIXVENT –TD fans include the com- bination of a powerful motor factory matched to a mixed flow impeller. This motor and impeller combination enables the MIXVENT- TD fans to deliver high airflow performances with the minimum of noise generation against high static pressures typically found in ducted ventilation systems. The unique design of the MIXVENT TD and TDx2 support brackets, allows the motor and impeller assembly to be fitted or removed wit- hout dismantling the adjacent ducting and therefore facilitating any installation or mainte- nance. The internal aerodynamic design of MIXVENT- TD fan enables the unit to generate large air volumes and pressures with the minimum of in-duct or radiated noise. An additional advantage of the MIXVENT TD fans is that they are fitted with direct connec- tion two speed motors as standard. In addi- tion, all motors are suitable for speed control regulation using electronic or auto-transfor- mer controllers. The MIXVENT-TD fans offer the ideal in-line duct fan solution for a wide range of HVAC ventilation applications. The MIXVENT system includes 3 ranges of products: – MIXVENT TD, Single Fan Unit – MIXVENT TDx2 , Twin Fan Unit – MIXVENT TD-T, Twin Fan Unit with Overrun Timer The MIXVENT-TD consists of eight (8) nomi- nal sized in-line fans. All models are specifically designed for direct connection in-line with industry standard diameter circular ducting. The MIXVENT-TDx2 range consists of two MIXVENT TD fans mounted in series to pro- duce almost twice the pressure of a single TD fan. The range consists of 5 nominal fan dia- meter sizes. The MIXVENT-TD-T consists of a range of five (5) nominal size TD fans (160, 250, 350, 500 and 800) fitted with an Run-On-Timer adjustable between 1 to 30 minutes. (The MIXVENT TD-T range is not suitable for speed control.) Accessories The MIXVENT System includes a specific range of accessories enabling the installation of different combinations of the MIXVENT TD and MIXVENT TDx2 fans, using models 350, 500, 800 and 1000. These combinations include: MIXVENT Twin Two MIXVENT TD fans mounted in parallel using the Twin Base Kit. Mounting the fans in parallel produces double the duty of one fan (at the same pressure). MIXVENT Twin x 2 Two MIXVENT TDx2 fans mounted in parallel using the Twin Base Kit. Mounting the fans in parallel produces double the duty of a single TDx2fan (at the same pressure). MIXVENT Twin x 3 MIXVENT-TD and MIXVENT TDx2 mounted in series using the Flange (MBR). The pressure achieved by this arrangement will produce almost three times that of a single unit (at the same ar volume). To compliment the MIXVENT System a range of electrical and additional mechanical acces- sories are available to complete the most demanding installations. The MIXVENT TD models are manufactured in tough reinforced plastic, except models 160, 1000, 1300 & 2000 which have a metal casing and are finished in a tough epoxy-polyester paint coating.

IN-LINE MIXED FLOW DUCT FANSMIXVENT-TD Fan Systems
The MIXVENT system has been designed tocompliment the MIXVENT-TD range of in-linefans. All MIXVENT –TD fans include the com-bination of a powerful motor factory matchedto a mixed flow impeller. This motor andimpeller combination enables the MIXVENT-TD fans to deliver high airflow performanceswith the minimum of noise generation againsthigh static pressures typically found in ductedventilation systems.The unique design of the MIXVENT TD andTDx2 support brackets, allows the motor and
impeller assembly to be fitted or removed wit-hout dismantling the adjacent ducting andtherefore facilitating any installation or mainte-nance.
The internal aerodynamic design of MIXVENT-TD fan enables the unit to generate large airvolumes and pressures with the minimum ofin-duct or radiated noise.
An additional advantage of the MIXVENT TDfans is that they are fitted with direct connec-tion two speed motors as standard. In addi-tion, all motors are suitable for speed controlregulation using electronic or auto-transfor-mer controllers. The MIXVENT-TD fans offerthe ideal in-line duct fan solution for a widerange of HVAC ventilation applications.
The MIXVENT system includes 3 ranges ofproducts:
– MIXVENT TD, Single Fan Unit– MIXVENT TDx2 , Twin Fan Unit– MIXVENT TD-T, Twin Fan Unit with
Overrun Timer
The MIXVENT-TD consists of eight (8) nomi-nal sized in-line fans. All models are specificallydesigned for direct connection in-line withindustry standard diameter circular ducting.
The MIXVENT-TDx2 range consists of twoMIXVENT TD fans mounted in series to pro-duce almost twice the pressure of a single TDfan. The range consists of 5 nominal fan dia-meter sizes.
The MIXVENT-TD-T consists of a range offive (5) nominal size TD fans (160, 250, 350,500 and 800) fitted with an Run-On-Timeradjustable between 1 to 30 minutes. (TheMIXVENT TD-T range is not suitable for speedcontrol.)
AccessoriesThe MIXVENT System includes a specificrange of accessories enabling the installationof different combinations of the MIXVENT TDand MIXVENT TDx2 fans, using models 350,500, 800 and 1000.These combinations include:
MIXVENT TwinTwo MIXVENT TD fans mounted in parallelusing the Twin Base Kit. Mounting the fans inparallel produces double the duty of one fan(at the same pressure).
MIXVENT Twin x 2Two MIXVENT TDx2 fans mounted in parallelusing the Twin Base Kit.Mounting the fans in parallel produces doublethe duty of a single TDx2fan (at the samepressure).
MIXVENT Twin x 3MIXVENT-TD and MIXVENT TDx2 mounted inseries using the Flange (MBR). The pressureachieved by this arrangement will producealmost three times that of a single unit (at thesame ar volume).

MBE, Electrical Heater BatteriesThe MBE electric heater battery sections are designed to be installed on the discharge side of the MIXVENT-TDfans. The units incorporate insulated (black heat) element rods (230V – 3W/cm2) with an automatic integratedoverheat thermostat (set at 90º C). This thermostat in turn is wired in series with an additional safety overheatmanual reset thermostat (set at 120º C). In the case of the unit overheating the second thermostat will switchthe unit off, after which the heater can then be "Reset" manually via the push button switch. All wiring termina-tions and connections are located on the side of the heater casing.The heaters are available for single phase (models MBE 100, 125 and 160) or three phase (models 200, 250 and315) electrical supply connection in conjuntion with appropriate circuit protection.
– All units are supplied with an IP43 rated wiring enclosure.– The minimum air velocity through the heater batteries must be >= 1.5 m/s.
A range of controllers accessories to accompany the electric heater range are available. These controllersaccessories modulate the heater output as a function of the required environmental temperature (see ElectricalAccessories section of this catalogue).
