Introduction — why the energizer matters

An electric fence is only as good as the energizer driving it. For medium-to-high security perimeters in Kenya — from gated estates and warehouses to medium farms and institutional compounds — the energizer must combine reliable power, intelligent diagnostics, alarm integration and resilience against Kenya’s varied climate. The Nemtek Druid 28 LCD is a dual-zone security energizer that fits this role: it provides monitored zones, useful diagnostics via an LCD, adaptive behaviour under load, and battery backup for power outages. Nemtek+1

This guide explains what the Druid 28 delivers, how it performs in Kenyan conditions, how to install and maintain it properly, where it fits compared with other energizers, and where to find manuals and demonstration videos to support installation teams. The goal is to give Kenyan buyers, security managers and farmers the detail they need to make a confident purchase and get reliable field performance. Nemtek

What is the Nemtek Druid 28?

The Nemtek Druid 28 LCD is a two-zone (dual-zone) security energizer in the Druid family. It’s intended for monitored perimeter protection where you want independent control and alarm reporting for two separate zones (for example, front and rear perimeters or two sides of a commercial plot). The Druid 28 features an LCD for status and diagnostics, internal battery backup, surge protection, tamper detection and configurable alarm outputs for integration with alarm panels or GSM modules. Nemtek+1

Technically, the publicly available data sheets and manuals show the Druid 28 provides robust high-voltage output with per-zone energy sufficient for medium perimeters (manufacturer figures list usable joules per zone and recommended conductor lengths). The unit is built to operate on 240V mains with a sealed lead-acid backup battery and is rated for continuous duty in commercial installations. Nemtek+1

Key specifications (what installers need to know)

Below are the most load-bearing technical details installers use to design a system. These figures are derived from Nemtek product documentation and distributor datasheets; always confirm the serial-specific test sheet with your supplier before final commissioning. Nemtek+1

  • Stored/usable energy: Nemtek publications list the Druid 28 as supplying in the region of ~3.7 joules usable per zone (measured at 500 Ω load) with an open-circuit voltage around 9,000 V. Actual usable energy varies by test conditions. Nemtek

  • Zones: 2 independently monitored and controllable zones (each can be set on/off or in differing voltage modes). Security Warehouse

  • Physical: typical Druid LCD enclosure dimensions ~400 × 270 × 125 mm; weight around 5.7 kg excluding battery, ~8.0 kg including 7Ah battery. IPx4 rating for splash resistance. Nemtek

  • Power: 230/240 V AC with internal charger and 12 V DC battery backup (standard 7Ah SLA). Standby time ≈ 24 hours on a fully charged battery under light/no load. Typical power consumption around 18–23 VA in normal operation. Nemtek+1

  • Protection & features: LCD diagnostics (walk test, alarm state colours), gate input, HV & earth monitoring, lightning/surge protection and programmable alarm outputs for integration with alarm systems. Manuals show programmable options and multi-energizer grouping for up to 4 zones with keypad control. Nemtek+1

How Druid 28 performs in Kenyan environments

Kenya’s climate and terrain vary from humid coastal zones to dusty semi-arid rangelands and wet highlands. The Druid 28’s adaptive diagnostics and sturdy design are suited to this variety when installed correctly. Adaptive features help maintain usable fence voltage under partial leakage or arcing (for example where vegetation or dust causes intermittent faults), and the LCD/walk-test speeds fault location across long runs — a major advantage when technicians need to troubleshoot remotely located fences. Nemtek+1

Battery backup matters in Kenya because mains interruptions are common in many regions. With a proper battery and good charging, the Druid 28 will keep critical security zones live during outages, and its alarm outputs can notify response teams if a fault occurs while the mains is down. For coastal installations, ensure the unit is mounted in a ventilated, sheltered enclosure to reduce corrosion risk. For arid areas, frequent dust checks and maintenance of insulators will sustain performance. Nemtek

Designing a Druid 28 system — practical guidelines

Designing perimeter protection around a Druid 28 is a systems task. Follow these practical steps:

  1. Define zones early — map front/back or left/right perimeters as separate zones so you get the most from the dual-zone monitoring. This isolates faults and helps incident location. Nemtek

  2. Size conductors to expected load — use politape or polirope for visibility and tensile strength if animals or humans could contact lines; choose conductor gauges and strand counts to match recommended lengths in Nemtek wiring tables. Data sheets provide guidance on expected kilometres per zone for different conductor types — use these as conservative planning values. Nemtek

  3. Earthing is critical — install multiple earth rods close to the energizer in moist soil if possible. Good grounding often improves measurable fence voltage more than increasing energizer size. Manuals emphasize earth rod placement and heavy gauge earth cabling. Nemtek

  4. Plan alarm integration — wire gate sensors and alarm outputs to your monitoring/GSM or armed response provider. The Druid 28’s programmable alarm modes allow you to trigger different responses for HV faults, earth faults, gate opens or tamper events. Nemtek

  5. Provide surge/lighting protection at the mains and consider surge diverters on the HV line to earth to reduce lightning risk. Manuals show best practice for diverters. Nemtek

Installation step-by-step (recommended process)

A professional installer should perform the Druid 28 installation, but here’s the high-level checklist technicians use:

  • Mount cabinet in a ventilated, sheltered position near the main earth spike — ensure the Druid is fixed to a secure wall or panel at a convenient service height. Nemtek

  • Drive at least three galvanised earth rods 1.8–2.4 m deep, bonded with heavy gauge earth conductor and connected to the energizer earth according to the manual. Good earthing reduces false alarms and increases fence effectiveness. Nemtek

  • Install conductors using UV-rated insulators and high-quality connectors. Keep fence line clear of vegetation and trim to prevent continuous leakage. Nemtek

  • Connect alarm & gate inputs (if used) to alarm panels or GSM modules; test alarm reporting and zone mapping using the Druid LCD walk-test. Use the manual to set programmable options for zone behaviour and alarm thresholds. Nemtek

  • Commission the fence by testing voltage at the energizer and at strategic far points under load. Document measured voltages and alarm thresholds for future troubleshooting. bobshop.co.za

Maintenance plan — keep the Druid 28 reliable

A simple, repeatable maintenance schedule keeps the system working:

  • Weekly to monthly visual checks of wires, insulators, and vegetation (frequency depends on local growth rates).

  • Monthly voltage checks at the energizer and at far fence points; log values and compare trends. Gradual voltage decline usually signals earth or corrosion issues. bobshop.co.za

  • Battery health check quarterly — verify charging voltage and replace sealed lead-acid batteries per manufacturer life expectancy (typical SLA 3–5 years depending on climate and cycles). Consider LiFePO4 upgrades where supported. Nemtek

  • Yearly service by a certified technician: test internal fuses, surge diverters, keypad functionality and program backups. Replace sacrificial lightning diverters after strikes. Nemtek

Troubleshooting common problems and fixes

Below are typical symptoms and practical fixes:

  • Symptom: low voltage at fence end but high at energizer. Likely cause: leakage along line or voltage drop from multiple strands. Fix: inspect for vegetation, broken insulators; reduce parallel strands or split fence into zones. Nemtek

  • Symptom: frequent alarms with no visible fault. Likely cause: intermittent earthing contact or moisture ingress. Fix: check earth rod connections, clean terminals, ensure enclosure seals and vents are intact. Nemtek

  • Symptom: battery not sustaining during outages. Likely cause: aged battery or heavy fence load. Fix: test battery capacity and replace if necessary; assess fence load and consider larger battery bank or auxiliary solar charging. Nemtek

If troubleshooting is inconclusive, consult the Druid installer manual for diagnostic codes and contact an authorized technician. Manuals and test reports are available online (links below). Nemtek

Druid 28 vs alternatives — how to choose the right energizer

Choosing between energizer models (Nemtek Druid 28, Druid 15, Stafix/Gallagher high-joule units, or farm energizers) depends on three practical variables:

  1. Required fence length and number of strands under real load (not advertised max km).

  2. Need for monitored zones and alarm integration. Druid family excels here. Nemtek

  3. Environment and power resilience needs — remote sites with outages may need larger battery banks or mains + solar hybrid solutions.

The Druid 28 stands out when you need dual-zone monitoring, good diagnostics, alarm outputs and moderate-to-high usable joule output without stepping up to much larger farm energizers. For very long wildlife fences or high-joule farm perimeters, larger multi-zone or farm-specific energizers are more appropriate. Regal Security+1
